All Implemented Interfaces:

IGLBindedResource, IGLRenderer, ISortableDraw

public class SphereVBO
extends DrawableVBO

Warning! Observed that the sphere will render weirdly for rare viewpoint when following GL setting is applied. painter.glDisable(GLConstants.GL_DEPTH_TEST) This is true when Quality.setAlphaActivated(false), in other word for Quality.Advanced.

 Color color)

Method Details

updateBounds

public void updateBounds()

Overrides:

updateBounds in class DrawableVBO

mount

public void mount(IPainter painter)

Description copied from interface: IGLBindedResource

Mount resources to gl context

Specified by:

mount in interface IGLBindedResource

Overrides:

mount in class DrawableVBO

draw

public void draw(IPainter painter)

Description copied from class: Drawable

Call OpenGL2 routines for rendering the object.

Specified by:

draw in interface IGLRenderer

Overrides:

draw in class DrawableVBO

drawSphereDirectWithDataFromArrays

protected void drawSphereDirectWithDataFromArrays(IPainter painter)

drawSphereWithDrawArrays

protected void drawSphereWithDrawArrays(IPainter painter,
 int slices,
 int stacks)

Draw one sphere. The VertexPointer and NormalPointer must already be set to point to the data for the sphere, and they must be enabled.

getBuilder

public static SphereVBO.VBOSphereMeshBuilder getBuilder(double radius,
 int stacks,
 int slices)

Allows retrieving or creating a sphere builder for this combination of parameters. The goal is to share a common mesh definition - hence a single pair of array - for a sphere parameter combination.

Parameters:

radius - sphere radius

stacks - number of latitudes

slices - number of longitudes

Returns:
