Class JoglRenderer

java.lang.Object
  render.Renderer
      render.jogl.JoglRenderer

public class JoglRenderer

extends Renderer

JOGL version of the software renderer, instead of drawing triangles into the buffer, we just push triangles into the graphics card.

Method Summary

void	addLight(double x, double y, double z, double lR, double lG, double lB) Add a light source where x,y,z are light source direction; r,g,b are light source color.
Geometry	getGeometry(int x, int y) Overloads the Renderer method to get a geometry, in our case this has to be called in the display thread, but our event handler system takes care of that.
net.java.games.jogl.GL	getGL()
net.java.games.jogl.GLU	getGLU()
net.java.games.jogl.util.GLUT	getGLUT()
boolean	getPoint(int x, int y, double[] xyz) get the coordinates of a point in world coordinates and put them into xyz if we did not hit anything, returns false this method also has to be called during the display thread.
int[]	init(int w, int h) Initializes the renderer.
void	render() Render the entire world for this frame.
void	setBgColor(double r, double g, double b) Set the background fill color.
void	setGLAmbient(float r, float g, float b)

setGLAmbient

public void setGLAmbient(float r,
                         float g,
                         float b)

init

public int[] init(int w,
                  int h)

Description copied from class: Renderer

Initializes the renderer.

Overrides:

init in class Renderer

Parameters:

w - framebuffer width

h - framebuffer height.

Returns:

framebuffer array.

addLight

public void addLight(double x,
                     double y,
                     double z,
                     double lR,
                     double lG,
                     double lB)

Description copied from class: Renderer

Add a light source where x,y,z are light source direction; r,g,b are light source color.

Overrides:

addLight in class Renderer

setBgColor

public void setBgColor(double r,
                       double g,
                       double b)

Description copied from class: Renderer

Set the background fill color.

Overrides:

setBgColor in class Renderer

render

public void render()

Description copied from class: Renderer

Render the entire world for this frame.

Overrides:

render in class Renderer

getGeometry

public Geometry getGeometry(int x,
                            int y)

Overloads the Renderer method to get a geometry, in our case this has to be called in the display thread, but our event handler system takes care of that.

Overrides:

getGeometry in class Renderer

Parameters:

x - x coordinate in the image

y - y coordinate in the image

Returns:

the geometry of the foremost object at that location

getPoint

public boolean getPoint(int x,
                        int y,
                        double[] xyz)

get the coordinates of a point in world coordinates and put them into xyz if we did not hit anything, returns false this method also has to be called during the display thread. Our event system handles this. Because of floating point error due to the way the points are saved in hardware, the result may not be totally correct (ie, if we expect z to be 0, we will get z to be close to 0 within an error rate which I have not calculated yet). Also this works currently with the default software renderer camera calculation It should not work with when you are doing user camera movement (may actually just need to remove one line).

Overrides:

getPoint in class Renderer
