Constructor Detail

GLNodeMarker

public GLNodeMarker(int index,
                    String name,
                    float radius,
                    int grid)

GLNodeMarker

public GLNodeMarker(int index,
                    String name)

Method Detail

setVisible

public void setVisible(boolean vis)

Determines whether the light source is visible, in the form of a small sphere, or not. This is just a visualization of the position of the light, and has no effect on the OpenGL lighting itself.

linkToTransformMatrix

public void linkToTransformMatrix(float[] trafo)

glInit

public void glInit(GLRenderContext gl)

Description copied from interface: GLRenderObject

Called during OpenGL initialization.

Specified by:

glInit in interface GLRenderObject

glRender

public void glRender(GLRenderContext gl)

Rendering a light means: set position, taking into account the current ModelView transformation. Optionally, a small sphere is rendered, to indicate the position of the light.

Specified by:

glRender in interface GLRenderObject
