matrix dimension for jit.gl.multiple

January 9, 2007 | 12:02 pm

Hi,

How many dimensions of matrix can I use for jit.gl.multiple ?
For example, nothing is drawn when I send "jit.noise 3 float32 3 3
3" (3 dimensions) as position_matrix. I can see 9 objects when I send
"jit.noise 3 float32 3 3"(2 dimensions).
What’s wrong ?

I attached the test patch.

I’m using MaxMSP 4.6.2, Jitter 1.6.2, Mac OS X 10.4.8 and MacBook Pro.

Thanks

Hi Masayuki,
jit.gl.multiple only processes 2 dimensional matrices right now. I’ll
consider this a feature request since it seems you want to do this.

I see.

Yes, please. It would be useful for 3D composition.
for example,
jit.expr @expr "snorm[0]" "snorm[1]" "snorm[2]"

Thank you.
