Constructor Details

DynamicIndexBuffer

public DynamicIndexBuffer(GLX glx,
 int numIndices)

Constructs a new dynamic index buffer

Parameters:

glx - GLX instance

numIndices - How many indices are in the buffer (number of indices, not bytes)

DynamicIndexBuffer

public DynamicIndexBuffer(GLX glx,
 int numIndices,
 boolean int32)

Constructs a new dynamic index buffer

Parameters:

glx - GLX instance

numIndices - How many indices are in the buffer (number of indices, not bytes)

int32 - Whether to use int32 size rather than int16 for index references (for large buffers > 65K)
