Hello
Is it faster to compute mat3 or mat4 operations in fragment programs ?
I’m asking so because I guess GPU is optimized for mat4 operations rather than mat3…
Thanks

mat4 * vec4 takes one instruction more than mat3 * vec3, if that answers your question.
Ok thanks, so if I can I should rather use mat3 operations.
Seems that Mat3Mat3 operations are faster than
3 Mat3Vec3 operations, interesting !
How can that be?!
