Hi there,
Not sure if bug reports are welcome here, if not please feel free to disregard. I noticed a problem with dgvoodoo which I believe has to do with the use of homogeneous coordinates in Glide 3.x. I grabbed the latest version from github. Basically the Y axis gets flipped, not really sure why this happens but it definitely doesn't happen on a real Voodoo3. Example vertex configuration:
grCoordinateSpace(GR_CLIP_COORDS);
grVertexLayout(GR_PARAM_XY, 0, GR_PARAM_ENABLE);
grVertexLayout(GR_PARAM_Z, 8, GR_PARAM_ENABLE);
grVertexLayout(GR_PARAM_W, 12, GR_PARAM_ENABLE);
grVertexLayout(GR_PARAM_RGB, 16, GR_PARAM_ENABLE);
grVertexLayout(GR_PARAM_A, 28, GR_PARAM_ENABLE);
Window is set to GR_ORIGIN_LOWER_LEFT. I can provide more details if needed.
