In this bit of code I wrote months ago,
I finally discovered the bug. Or two. Can you?
if (mRendererType->IsGL())
{
// different 4x4 matrix convention requires transpose
GLfloat m[16];
for (int j=0; j<4; j++)
{
for (int i=0; j<4; j++)
{
m[i*4+j] = inMatrix->value[i][j];
}
}
glMultMatrixf(&m[0]);
status = kQ3Success;
}
else if (mRendererType->IsQ3())
{
status = Q3MatrixTransform_Submit(inMatrix, mView);
ThrowIf_(status != kQ3Success);
}
return status;
So, BrickDraw3D has working OpenGL rendering mode now.
Ugh.
