Package gaiasky.scene.system.render.draw

Class PointCloudRenderer

java.lang.Object

gaiasky.render.system.AbstractRenderSystem

gaiasky.render.system.ImmediateModeRenderSystem

gaiasky.scene.system.render.draw.PointCloudRenderer

All Implemented Interfaces:

com.badlogic.gdx.utils.Disposable, IObserver, IRenderSystem

Direct Known Subclasses:

ParticleSetPointRenderer

public abstract class PointCloudRenderer
extends ImmediateModeRenderSystem
implements IObserver

Contains some common code to all point cloud renderers and some scaffolding to make life easier. Should be used by point clouds that render their particles as GL_POINTS.

Method Details

initVertices

protected void initVertices()

Specified by:

initVertices in class ImmediateModeRenderSystem

addVertexAttributes

protected abstract void addVertexAttributes(com.badlogic.gdx.utils.Array<com.badlogic.gdx.graphics.VertexAttribute> attributes)

Adds the required vertex attributes for this renderer to the given list

Parameters:

attributes - The list of attributes

buildVertexAttributes

protected com.badlogic.gdx.graphics.VertexAttribute[] buildVertexAttributes()

Builds the vertex attributes array and returns it

Returns:

The vertex attributes array

offsets

protected abstract void offsets(ImmediateModeRenderSystem.MeshData curr)

Parameters:

curr - The current mesh data

addMeshData

protected int addMeshData(int maxVerts)

Adds a new mesh data to the meshes list and increases the mesh data index

Parameters:

maxVerts - The max number of vertices this mesh data can hold

Returns:

The index of the new mesh data

addMeshData

protected int addMeshData(int maxVerts,
 int maxIndices)

Adds a new mesh data to the meshes list and increases the mesh data index

Parameters:

maxVerts - The max number of vertices this mesh data can hold

maxIndices - The maximum number of indices this mesh data can hold

Returns:

The index of the new mesh data

preRenderObjects
