Package org.lwjgl.opengl

Class ARBTransposeMatrix

java.lang.Object

org.lwjgl.opengl.ARBTransposeMatrix

public class ARBTransposeMatrix
extends java.lang.Object

Native bindings to the ARB_transpose_matrix extension.

New functions and tokens are added allowing application matrices stored in row major order rather than column major order to be transferred to the OpenGL implementation. This allows an application to use standard C-language 2-dimensional arrays (m[row][col]) and have the array indices match the expected matrix row and column indexes. These arrays are referred to as transpose matrices since they are the transpose of the standard matrices passed to OpenGL.

This extension adds an interface for transfering data to and from the OpenGL pipeline, it does not change any OpenGL processing or imply any changes in state representation.

Promoted to core in OpenGL 1.3.

Method Detail

glLoadTransposeMatrixfARB

public static void glLoadTransposeMatrixfARB(java.nio.FloatBuffer m)

Sets the current matrix to a 4 × 4 matrix in row-major order.

The matrix is stored as 16 consecutive values, i.e. as:

a1	a2	a3	a4
a5	a6	a7	a8
a9	a10	a11	a12
a13	a14	a15	a16

Parameters:

m - the matrix data

glLoadTransposeMatrixdARB

public static void glLoadTransposeMatrixdARB(java.nio.DoubleBuffer m)

Double version of LoadTransposeMatrixfARB.

Parameters:

m - the matrix data

glMultTransposeMatrixfARB

public static void glMultTransposeMatrixfARB(java.nio.FloatBuffer m)

Multiplies the current matrix with a 4 × 4 matrix in row-major order. See LoadTransposeMatrixfARB for details.

Parameters:

m - the matrix data

glMultTransposeMatrixdARB

public static void glMultTransposeMatrixdARB(java.nio.DoubleBuffer m)

Double version of MultTransposeMatrixfARB.

Parameters:

m - the matrix data
