需要帮助扩展O3D

Question

I have been having trouble find much documentation on o3d (not too surprisingly). Does anyone know how to scale my x in o3d?

Answer 1

In the o3djs.math module there is a function:

o3djs.math.matrix4.scaling = function(v) ...

where "v" is a vector. So if you have a current transformation matrix you could do:

var scaleMatrix = o3djs.math.matrix4.scaling( [0.6, 1, 1] );
var newMatrix = o3djs.math.mulMatrixMatrix4(scaleMatrix, currMatrix);

The "newMatrix" would scale the X dimension of the cube by 0.6 and then apply "currMatrix" after that.
