Method Detail

drawStart

void drawStart(int mask)

Resets the vertices back to zero and sets the types of changes that will be made during the drawing cycle. In some implementations the data will be destroyed in any buffer referenced in the mask.

Parameters:

mask - The bitmask of things which can change.

drawStart

void drawStart()

Resets the vertices back to zero and sets the types of changes that will be made during the drawing cycle. This assumes all the data is going to change. Use the drawStart(mask) version if you will only be changing some of the data.

newVertex

int newVertex()

Starts a new vertex to be updated. This must be called before setting the vertex information.

Returns:

The index of the new vertex.

drawEnd

void drawEnd()

Ends the drawing cycle and commits the geometry changes to the 3d card. The number of vertices will be set.
