Class MatrixStack
java.lang.Object
net.minecraft.client.util.math.MatrixStack
A stack of transformation matrices used to specify how 3D objects are
translated, scaled or
rotated in 3D space. Each entry consists of a
position matrix and its
corresponding normal matrix.
By putting matrices in a stack, a transformation can be expressed relative to another. You can push, transform, render and pop, which allows you to restore the original matrix after rendering.
An entry of identity matrix is pushed when a stack is created. This means that a stack is empty if and only if the stack contains exactly one entry.

scale
public void scale(float x, float y, float z) Applies the scale transformation to the top entry.- Implementation Note:
- This does not scale the normal matrix correctly when the scaling is uniform and the scaling factor is negative.
