jit.gl.multiple rotation and scaling transform order

Hi everyone!

Fairly simple question…I think.

When using jit.gl.multiple, it rotates first, then scales. With jit.gl.gridshape, it scales first, then rotates.

See patch for what I mean. Is there any way to alter this so that jit.gl.multiple will do things the same as jit.gl.gridshape? (This seems to be the case for both glparams rotatexyz and rotate)

Thanks, Dan

hi dan. in order for the gl.multiple to apply transforms in the same manner as gl.gridshape, you need to do your scaling with a matrix, and not the target gl.gridshape attribute.

the order attributes are listed in the @glparams attribute determines the order the transforms are applied.

so “@glparams position rotate scale” will mimic the order of transforms of the regular gl.gridshape.

hope this helps.

That was sure simple, thanks!
