* adapt to the new texture interface and fix the identvshader.rodri2024-07-051-11/+18
| | | | | | | | the identvshader was used for the toon shader as well, and that forced it to do a light computation when its fragment shader won't ever use it. split it in two vshaders, each for their own purpose, so we don't get slow identity rendering.
* med,vis: fix normal map sampling.rodri2024-07-041-2/+3
| | | | | | recent changes in libgraphics assume every texture resides in an sRGB color space, which is not the case for material resources like normals.
* vis,med: make qball rotations position-independent.rodri2024-06-161-3/+3
| | | | | the camera no longer needs to be on the first quadrant for the qball to work.
* vis: add some instrumentation to debug the framebuffers.rodri2024-06-141-1/+37
|
* use the new modulapt3 functions. don't clamp in the shaders.rodri2024-06-131-49/+30
|
* add skyboxes based on cubemaps.rodri2024-06-061-14/+24
|
* vis: same as previous commit, and add normal mapping to the phong shader.rodri2024-06-041-29/+53
| | | | | implemented tangent space normal mapping and now diablo3 looks sick!
* get rid of rendering latency by decoupling it from i/o.rodri2024-05-231-12/+28
| | | | | | | | | | | i was using a single alternator to mux both i/o and drawing in a single proc, and avoid locking. the problem is that it causes a fight to break up every time there's any input (steady 100Hz) or a lot of drawing requests from the renderer (up to 60Hz.) i added a drawproc to handle exclusively drawing requests, and a drawing lock for UI widgets that kidnap the display.
* fix the gouraud shader. improve the cube generator in med.rodri2024-05-231-28/+32
| | | | | | | | gouraud wasn't being applied when the vertex had no material, now it just takes the defaults. also added a new primtest.obj to visualize all the primitives in a single model.
* add a triangular basis and clamp the fov to [1,180]°.rodri2024-05-161-2/+2

* use real lengths in solar. bring a qball for vis.rodri2024-05-141-24/+34

* vis: print pipeline timings to stderr when profiling.rodri2024-05-071-0/+6

* adapt to the recent changes in libgraphics. add new test files.rodri2024-05-031-27/+19
