There is no transpose for mat3 #36

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The calculation of a normal transformation matrix requires a transpose for 
mat3. Currently this can be worked around by doing:

    var normMat = mat3.create();
    mat4.toInverseMat3(mvMatrix, normMat);
    normMat2 = mat3.toMat4(normMat);
    mat4.transpose(normMat);

but this is just annoying. The transpose should be done on the mat3, not the 
mat4.
