* change the raster format to RGBA32. draw to any image format. clean up.rodri2024-09-117-53/+181
| | | | | | | | | | | | | | | | got rid of the bullshit dance between XRGB32 and RGBA32, now all rasters are RGBA32 and premultiply alpha before loading up an image and drawing over the destination. this lets the user compose their own scenes with correct transparency. no more mediocre clearcolor. as a consequence drawing got slower, but if i get the turbo drawing pool working properly that should go away. textures also take alpha pre-multiplied channels into account, dividing them when sampling, so loading transparent textures will show the correct colors.
* fix a use-after-free when profiling rasterizer times.rodri2024-09-104-4/+99
| | | | | | | | | | this commit also includes the turbo drawing pool. the experiment was successful in getting reasonable drawing times to a fullhd image, but the process causes glitches when moving the objects around, which is unacceptable. it's been commented out for now.

* implement a general raster interface for the framebuffers.rodri2024-08-296-108/+345
| | | | | | | | | | | | | | | got a bit tired of having to add a ulong *buf every time i needed to get some data out of the shaders, so i made it possible to create as many extra buffers as needed, which then can be addressed from the fragment shader and drawn using the same drawing routines that were used for the color buffer. these so called Rasters are very similar to the OpenGL FBOs, in case you are familiar, but we address them by strings instead of numbers. and they can also be used as textures if you create one (see alloctexture) and then memdraw into it after every shot.
* replace f?(min|max) functions with type-agnostic macros.rodri2024-08-273-28/+2
| | | | | this simplifies the code and serves as another shadeop to use on application shaders.
* scene: add a method to get an entity from a scene.rodri2024-08-252-0/+13

* methods to add primitives and materials to a Model.rodri2024-08-233-3/+25

* unify drawing routines and add clipped fb drawing support.rodri2024-08-174-33/+70
| | | | | | now changing the viewport offset will correctly show the portion of the framebuffer that's visible, including support for upscaled views.

* experimental A-buffer implementation.rodri2024-08-104-15/+132
| | | | | | | | | very simple, without anti-aliasing, made for getting OIT (order independent transparency) rendering of arbitrary objects. also added switches for blending, depth testing and the A-buffer to the camera.

|
* fix line interpolation during rasterization.rodri2024-08-024-7/+46
| | | | | | | vertex attributes were not being updated after clipping with their corresponding work rectangles, nor when reordering the points before rasterization, which caused serious artifacts.

|
* fix stack overflow, skybox fov sensibility and scene duplication.rodri2024-07-154-15/+30
| | | | | | | | | putting the duplicate camera in a local variable turned out to be a bad idea. bring the dynamic version back. the skybox rendering was affected by the camera fov, which made it look like it was not really at infinity, so set it always to 90°.
* initial viewport upscaling support.rodri2024-07-143-2/+76

|
* fix the geometry glitches when moving things around.rodri2024-07-138-145/+260
| | | | | | | | | | it's possible for interactive programs to keep updating the geometry of the scene during rendering, which caused primitives to look deformed or shattered in the final image. to avoid this we take a snapshot of the current state of things (scene and camera), and render based on that copy.
