Interface Scene.PMVMatrixSetup

Enclosing class:

Scene

public static interface Scene.PMVMatrixSetup

Interface providing a method to setup PMVMatrix's GLMatrixFunc.GL_PROJECTION and GLMatrixFunc.GL_MODELVIEW.

At the end of operations, the GLMatrixFunc.GL_MODELVIEW matrix has to be selected.

Implementation is being called by Scene#setupMatrix(PMVMatrix, int, int, int, int) and hence Scene.reshape(GLAutoDrawable, int, int, int, int).

Custom implementations can be set via Scene.setPMVMatrixSetup(PMVMatrixSetup).

The default implementation is described below:

• GLMatrixFunc.GL_PROJECTION Matrix
  • Identity
  • Perspective Scene.DEFAULT_ANGLE with Scene.DEFAULT_ZNEAR and Scene.DEFAULT_ZFAR
  • Translated to given Scene.DEFAULT_SCENE_DIST
  • Scale (back) to have normalized plane dimensions, 1 for the greater of width and height.
• GLMatrixFunc.GL_MODELVIEW Matrix
  • identity

Method Summary

Modifier and Type	Method	Description
void	set(PMVMatrix pmv, Recti viewport)	Setup PMVMatrix's GLMatrixFunc.GL_PROJECTION and GLMatrixFunc.GL_MODELVIEW.
void	setPlaneBox(AABBox planeBox, PMVMatrix pmv, Recti viewport)	Optional method to set the Scene.getBounds() AABBox, maybe a nop if not desired.

Method Detail

set

void set(PMVMatrix pmv,
         Recti viewport)

Setup PMVMatrix's GLMatrixFunc.GL_PROJECTION and GLMatrixFunc.GL_MODELVIEW.

See Scene.PMVMatrixSetup for details.

At the end of operations, the GLMatrixFunc.GL_MODELVIEW matrix is selected.

Parameters:

pmv - the PMVMatrix to setup

viewport - Rect4i viewport

setPlaneBox

void setPlaneBox(AABBox planeBox,
                 PMVMatrix pmv,
                 Recti viewport)

Optional method to set the Scene.getBounds() AABBox, maybe a nop if not desired.

Will be called by Scene.reshape(GLAutoDrawable, int, int, int, int) after set(PMVMatrix, Recti).

Parameters:

planeBox - the AABBox to define

pmv - the PMVMatrix, already setup via set(PMVMatrix, Recti).

viewport - Rect4i viewport
