Method Detail

addBaseAttributes

public static void addBaseAttributes(com.badlogic.gdx.utils.Array<com.badlogic.gdx.graphics.VertexAttribute> attributes,
                                     int textureCount,
                                     boolean position3D,
                                     boolean textureCoordinates3D)

Generate vertex attributes suitable for multi-texturing and vertex color. 32 bit floats are used for each position component and texture coordinate. The four color components are packed into a single 32 bit float.

Parameters:

textureCount - The number of textures to support.

position3D - Whether the position attribute should include a Z component.

textureCoordinates3D - Whether the texture coordinate attribute(s) should include a third component.

attributes - The array to add the vertex attributes to. They are added with position and color in the first two available positions, followed by texture coordinates.

generateGenericVertexShader

public static java.lang.String generateGenericVertexShader(int textureCount)

generateGenericFragmentShader

public static java.lang.String generateGenericFragmentShader(int textureCount)

populateQuadrangleIndices

public static void populateQuadrangleIndices(short[] triangles)

Populates an array of triangle indices for quadrangles made up of two triangles. The indices are ordered such that they produce counter-clockwise-wound triangles if the vertices are ordered as follows:

2--3
| /|
|/ |
1--4

Parameters:

triangles - The array that will be filled with triangle indices.
