With hopefully minimal/no changes to programs, and big speed increases. Rene Dudfield. illumen@yahoo.com TODO: First compatibilty, optimization, then next gen. NOTE: there are some more TODO's sprinkled througout the code Compatibilty. - need to implement all of screens methods. - test on more games. - chimp(works). - pyddr(doesn't work). - I think it has to do with the different format images. - I think a conversion may not be working properly. - bleten(works). - works, but is kinda slow when lots of images change. - need to work on a scaling method which uses opengl. - need to not use tostring() for making textures(slow). - work on caching some more, so that there is a texture cache as well. - so that images don't need to be uploaded to the card all the time. - yass(don't know). - a better way to detect when an images contents have changed. - probably a wrapper around surface, and surfarray which marks the image as dirty. - split sprites larger than 256x256 into multiple smaller textures. - for some older 3d cards. - should figure out how to detect max texture size. - support 8 and 16 bit and color keyed textures. - Make sure textures are cleaned up correctly in all cases. - Beta test on a wide number of machines. - Make it work correctly when the screen size changes. Optimization. - Put multiple sprites onto the same texture, and use uv coords for drawing particular sprites. This is a *big* optimization. - especially for animation. - move all texture management into the group, so as to optimize texture drawing more easily. - Have a set max number of textures to use in a texture cache. - Cache textures - optimize the screen.blit function, and some others: - with blit, only update a certain part of the texture which was actually blitted. - screen.fill - Group drawing by the same texture(less texture binds). - Try display lists to see if better performing. - try vertex buffers for better performance. - Make 1000+ sprite test case, and optimize for this case. - Update texture instead of replacing it when: - some pixels change in an image. - when the image changes and the old one isn't to be used anymore. - How to know this? Next gen. - Add scaling, rotation, other effects to a sprite class. - use caching of images for sdl, and straight opengl calls(eg glRotate etc). - shadows from sprites onto the background. - Make classes/optimize existing classes for drawing: - scrollers, tile maps, height maps, - 3d animated characters (http://www.py3d.org/py3d_zwiki/milkshape3d_animation) - doomIII clone ;) """ # search and replace this for __debug__ for a bit of a speed increase in -O _debug__ = 0 #Import Modules import os, pygame from pygame.locals import * from OpenGL.GL import * #from OpenGL.GLUT import * from OpenGL.GLU import * import time """ old_glMatrixMode = glMatrixMode def glMatrixMode(*args): modes = {GL_PROJECTION: "GL_PROJECTION", GL_MODELVIEW: "GL_MODELVIEW"} if _debug__: printw( glMatrixMode, modes[args[0]]) return apply(old_glMatrixMode, args) old_glTexSubImage2D = glTexSubImage2D def glTexSubImage2D(*args): if _debug__: printw( "glTexSubImage2D"+ str(args[:-1])) apply(old_glTexSubImage2D, args) """ #from _opengl2 import glVertexPointer, glColorPointer, glNormalPointer, glTexCoordPointer #from _opengl2 import glVertexPointer, glColorPointer, glNormalPointer#, glTexCoordPointer #from _opengl2 import glTexCoordPointer """ In order of easyness. make a draw method for the group. replace screen.blit with one which will work. make an update method.

Blit all smaller tiles to an offscreen buffer then blit one big image to the screen. This can be faster on some screens/computers. * Different tile sizes. * different sizes on the same map. * Join maps together easily. * Different drawable sizes. Ie different camera views. * Be able to be used with pygame or pyopengl. * Different camera modes: * jump scrolling, * jump the map in blocks. Like ten pixels at a time. * smooth scrolling, * every pixel the camera moves the tiles move. * smooth-jump scrolling. * Mostly the screen stays still. When the character nears the edge everything stops moving while the maps scrolls over a little way. * centered camera. * Can center the camera on * Looping Map Edges * Paralax scrolling. * Moving layers at different speeds. * Multiple views of the map. * miniview of the map. Perhaps using a scaled version or one pixel per tile. * minimize overdraw. * using dirty rectangles. * for alpha images precalculate 'full rects'. * That is like a bounding box in the middle where the area is full. * think about using a coverage buffer. * animated tiles will probably always need to be redrawn(unless it's the same frame). * Overlapping tiles. * As well as overlapping whole maps. For joining maps together. * Layers/Z ordering. * draw characters by descending y value on same layer. * for certain types of games: see for explanation: * http://www.gamedev.net/reference/programming/features/gpgenesis9/page7.asp * line of sight tests between tiles and pixels/rects. * collision detection between tiles and pixels/rects. * some tiles may be pass through. * tiles on different layers may be collidable, others not. * fog of war. * darkening/lightening of areas. * Rotatable tiles. * scalable tiles? Other transforms needed? * Easy layer toggling. * So eg when you go inside a building the roof comes off and you can see inside. = Implementation ideas = * Use pygame sprites and sprite groups. * could then reuse lots of code... optimize in one place. Speed development. * think of camera movement as simply moving a sprite group in a certain way. * Use a quad tree for the collision detection. * Could use it for moving, and non moving. * Left to right, or top to bottom scrollers can be optimized in different ways. = Some map editors = The tile combie(or engine if you want) should have most of the features that these map editors contain. http://tilestudio.sourceforge.net/ http://www.tilemap.co.uk/ = A discussion about features = background tiling, layers, collision detection between layers and stuff (rect and pixel) paralax scrolling animation of background/sprites line of sight tests between tiles and pixels based on layer compositions and such eek, that's a lot of stuff good stuff :) separate environmental and UI layer systems what do you mean? so you can draw your UI without worrying how height your environments layers are the UI layers are alwayrs on top ah, cool basically, just 2 lists for heights auto-shadowing for sprites is good indeed, that'd be cool doing like angled skews on the images, and drawing them on the ground layer so you dont have to have separate shadow images for them nice or just auto positioning the same image, but based on heigth of the sprite so like a flying ship has its shadow in the real place, and its in its height-adjusted place, like zaxxon which basically just means you have a transformation for height built in, and use a sort of worrld coords and translated drawing coords aah which makes sense so you should have parameters to what your viewing perspective is, so they can adjust it based on how their art is rendered like: 1.5:1.0 or something you could also have layer toggling like i did in VT, where if you go into a building, it switches what the background tiles are. and if you change floors, it also does that ah, that sounds nice too but that may be a bit specific. though, you could make the design so its possible to rotate through BG tile maps specifically, like theyre layered and do a fall through if the current selected one doesnt exist to the default background map, which has all its spaces mapped sorta an "optional current level background" good for things where people take stairs, and you still want the ground of things outside buildings and such im running out of stuff ive thought about for tiling engines hehe. that's all stuff I didn't think about :) i want to retire im pretty happy doing fuck all all the time now heh having layers greyed out would be good hehe. mostly I'm happy doing fuck all too :) optional layers? or you mean something else?

Multiply the bones down the heirarchy. child.absolute = parent.absolute * child.relative Per frame stuff. Get current time in animation. From Time2Keyframe_Map grab two keyframes on either side of current time. For every absolute quat: Interpolate between two keyframes: t1 = current_time_in_animation - kf_a.time t2 = kf_b.time -kf_a.time slerp = t1/t2 frame_now = quat_slerp(kf_a.absolute, kf_b.absolute, slerp) Generate the matrices for each absolute quat. Transform each absolute matrix by the local2world_transform. Transform verts of the mesh: For vertex which is affected by one bone: For each absolute matrix transform its verts. If the vert is only affected by one bone: Multiply the vert by the absolute matrix. else: somehow interpolate the different bones. - TODO: ^ - maybe this could be done in the slerp? - storing some extra absolute quats for the verts affected by multiple ones. - this is where bone weights can fit in. For now we will only support one bone per vertex. Alternate way to transform the skin: For each vertex: look at the weight structure. ulong32 boneIndices - 4 indices to bones. ulong32 weights - 4 weights. --------------------------------------------------------------------- Optimizations. --------------------------------------------------------------------- When a key frame does not have any translations the transform of the vertices can be optimized to only use a 3x3 rot, instead of a 4x4. - There may be other optimizations depending on the bones state. - Maybe we could store a BONE_STATE int which will allow us to quickly identify a type of bone? This would allow us to quickly see if the bone has no translation. - We could group bones of similar nature together to make the transforms quicker. Eg all bones with no translation part could be stuck together. - Remember that we need to apply a local2world transform to all of the different absolute matrices. We may be able to cache certain different transforms. - I'm pretty sure there will be many repeated transforms. A cheap way to interpolate between keyframes would be linear using the mesh's verts. This would involve calculating the mesh for each key frame, and then interpolating between each vertex in meshes a, and b. Perhaps this could be an optional thing. To be used for slow computers, when a character is far away, or when the difference in time or movement of the character is really small. A downside to this is that you need to keep at least three sets of the mesh around at any time. An upside to this is that interpolation can be done on lighting values too. --------------------------------------------------------------------- --------------------------------------------------------------------- TODOS: Future todos: - have keyframe data for seperate parts of the skeleton. - eg make the hand have it's own keyframes. - This would complicate how to construct the absolute quats. - You would recalculate down from the animation for that part. - so if the arm was using some extra ones we'd go from there. - Probably not so useful until the animation tool supports it. - Incorporate bone weights into it. - Milkshape doesn't support these, however others(characterfx) do. - Look at the different ways to accelerate these with hardware. - ati, and nvidia have things to do this from geforce up. --------------------------------------------------------------------- --------------------------------------------------------------------- Dependencies - a list of different dependencies that need to be considered. - helps with caching different things. --------------------------------------------------------------------- --------------------------------------------------------------------- OLD Order of the operations.

""" """ A scene graph which will contain all sorts of information about 3d scenes. Advantages this method will give you. - Allow importers and exporters to be written independantly. Just write an importer and you can take advantage of all the exporters. - Able to choose a disk based, or memory based conversion. - Don't have to support all of a 3d format, can support only parts of a format. This is necessary as development nearly always happens incrementally with 3d format converters. This means importers and exporters will have to specify which elements that they support. - Extensibility: the system is designed to be extensible. So that if new 3d formats are added they will not affect the old ones. This is done by having all importers and exporters contain a list of features which they support. Here is an example of how it would all work: First the importer and exporter(s) will tell the middle object which features that they support(or are interested in). The importer will read in what of the 3d format it understands, then pass the 3d data onto the middle object. Also passing on the features which the importer has imported. - Support multiple exporters being used at once. But only one importer being used at once. Multiple exporters will be useful to save having to do the import step multiple times when exporting to lots of formats. - Each exporter will be responsible for setting which features that it wants to export. That way it is possible to - A feature can be any sort of 3D data. We want to support as much different data as possible. Here is a list of 3d data that I can think of: = mesh data, = vertex, face lists. = vertex shading information. = per vertex, pre face UV information. = Scene graph information( this will be hard ). - It could be a graph of indicies to other objects. Maybe a tuple of (feature_name, index into list) - Not sure how inheritance will be handled. = bezier lines, and patches. = nurb lines and patches. = Texture mapping info. = cameras = lights (point, spot, omni, ambient). = image maps for terrain. = Material information. - color maps. - animations. - bump maps. - alpha maps. - smoothing. - specularity. - May provide a heap of helper functions, to help make converting the data easier. Providing different views of the intermediate data. eg. converting a mesh made up of 4, and 3 sided polygons into a mesh made up of only 3 side polygons. Here is a list of helpers: = ngons to triangles. = curve patches to triangles. = per face, to per vertex uv mapping conversions. = scaling. = rotation. = converting which coordinates are up, sideways and depth. - May need to implement a disk based dictionary, and a disk based list. As the shelf object which uses a database as a backend is pretty lame. It can only store objects of a certain size. Also they are only dicts, not lists. - Perhaps to save on memory, we could write certain features to disk(using pickle) whilst the other data is being converted. - Importers, and exporters don't necessarily need to read or write to files. eg. They may comunicate directly with a 3d editor, or a game engine. They could use a COM, CORBA, or xml rpc interface. - Should try and make use of other converter libraries, eg lib3ds. - importers and exporters should be able to do things like eg. only export frame 34 of the animation. Probably have to expand on the feature passing idea for this. Diagram of how feature information moves around: user --wanted exporters--> middle_obj user --wanted features for exporters--> middle_obj user --wanted features--> middle_obj importer --supported features--> middle_obj middle_obj --features to export--> exporters - Reduce the number of unnessesary calculations. One way to do this is to have the importers and exporters know which way certain things are defined. Eg. the coordinate systems: in one format x may be depth, and in another format x may be depth but comming into the screen. ei. if two formats both use z+ as depth then there is no need to transform the coordinates when putting them into the middle object. NOTE: supplying all different types of stores in the middle object should not be mandatory. There will be a default for the middle object which all importers should support. NOTE: This information would be stored with each feature. Eg, Meshes.Triangles.PointOrder.Supported.Value = ["clockwise", "anticlockwize"] Meshes.Triangles.PointOrder.Default.Value = "clockwise" - If Conversions have to be done on data, make sure that the conversions also change other data which is dependant on it. The only example of this that I can think of at the moment is Indexes to things. eg. face list index to a heap of points. Maybe we should keep some dependancy information somewhere. Think about this some more. Maybe too much effort. - Keep documentation of all the features. Documentation of every feature will be kept in a master feature list. The master feature list will be generated from the importers,exporters, and the middle object. The middle object will be updated sporadically when new features come around. The documentation of the features will also be taken from - Keep a central repository of all the different features. Supply a report of which importers/exporters support what. These need to be automated. The feature objects of a importer/exporter/middle_object are python objects which contain __doc__ strings. - With (importers/exporters) and the middle object, the feature objects are used differently. The middle object uses features to store not only the documentation on the various features, but also data itself. - Make some test importers, and exporters. A test importer will fill up the middle object with what ever data the exporter asks of it. A test exporter will ask the middle object for some data to export. If we can get an test exporter, and importer which supports _ALL_ the features, then testing will be easier, and there will be some base implementations for people to look at. - A validate format function for each format may be useful. One function could be used to validate the import and export plugins. It is optional to implement this. Quality plugins implement this ;). - A DoValidation() method for importers and exporters may be useful. This way an importer/exporter has the option of validating the data or not. Not validating the data may be a speed increase. Both in speeding up the conversion and speeding up the writing of the plugin. Validating data during the conversion may also be faster than doing the validation as a seperate pass. It is optional to implement this. Quality plugins implement this ;).
