CLASS net/minecraft/class_4587 net/minecraft/client/util/math/MatrixStack COMMENT A stack of transformation matrices used to specify how 3D objects are COMMENT {@linkplain #translate translated}, {@linkplain #scale scaled} or COMMENT {@linkplain #multiply rotated} in 3D space. Each entry consists of a COMMENT {@linkplain Entry#getPositionMatrix position matrix} and its COMMENT corresponding {@linkplain Entry#getNormalMatrix normal matrix}. COMMENT COMMENT
By putting matrices in a stack, a transformation can be expressed COMMENT relative to another. You can {@linkplain #push push}, transform, COMMENT render and {@linkplain #pop pop}, which allows you to restore the COMMENT original matrix after rendering. COMMENT COMMENT
An entry of identity matrix is pushed when a stack is created. This COMMENT means that a stack is {@linkplain #isEmpty empty} if and only if the COMMENT stack contains exactly one entry. FIELD field_20898 stack Ljava/util/Deque; METHOD method_22903 push ()V COMMENT Pushes a copy of the top entry onto this stack. METHOD method_22904 translate (DDD)V COMMENT Applies the translation transformation to the top entry. ARG 1 x ARG 3 y ARG 5 z METHOD method_22905 scale (FFF)V COMMENT Applies the scale transformation to the top entry. COMMENT COMMENT @implNote This does not scale the normal matrix correctly when the COMMENT scaling is uniform and the scaling factor is negative. ARG 1 x ARG 2 y ARG 3 z METHOD method_22907 multiply (Lorg/joml/Quaternionf;)V COMMENT Applies the rotation transformation to the top entry. ARG 1 quaternion METHOD method_22908 (Ljava/util/ArrayDeque;)V ARG 0 stack METHOD method_22909 pop ()V COMMENT Removes the entry at the top of this stack. METHOD method_22911 isEmpty ()Z COMMENT {@return whether this stack contains exactly one entry} METHOD method_23760 peek ()Lnet/minecraft/class_4587$class_4665; COMMENT {@return the entry at the top of this stack} METHOD method_34425 multiplyPositionMatrix (Lorg/joml/Matrix4f;)V COMMENT Multiplies the top position matrix with the given matrix. COMMENT COMMENT
This does not update the normal matrix unlike other transformation
COMMENT methods.
