pmvMatrix can make a matrix by using glTranslate/glRotate etc. FFP instructions.
Camera setup esample
pmvMatrix.glMatrixMode(GLMatrixFunc.GL_PROJECTION); pmvMatrix.glLoadIdentity(); pmvMatrix.gluPerspective(fov, aspect, zNear, zFar); pmvMatrix.glMatrixMode(GLMatrixFunc.GL_MODELVIEW); pmvMatrix.glLoadIdentity(); pmvMatrix.glRotatef(360 - pitch, 1, 0, 0); pmvMatrix.glRotatef(360 - yaw, 0, 1, 0); pmvMatrix.glRotatef(360 - roll, 0, 0, 1); pmvMatrix.glTranslatef(-position.x, -position.y, -position.z); pmvMatrix.update();
Using with shaders esample
GLUniformData pmvMatrixUniform;
init code...
PMVMatrix pmvMatrix = ...;
state.attachObject("pmvMatrix", pmvMatrix);
pmvMatrixUniform = new GLUniformData("pmvMatrix", 4, 4, pmvMatrix.glGetPMvMatrixf());
state.ownUniform(pmvMatrixUniform);
state.uniform(gl, pmvMatrixUniform);
display code...
state.uniform(gl, pmvMatrixUniform);
