Detailed Description

Base interface for all DrawElements* sub classes.

Implements the index-type-independent interface of the class. That is you can cast to DrawElementsBase* and access its members without needing to know whether the actual class is a vl::DrawElementsUInt, vl::DrawElementsUShort or vl::DrawElementsUByte.

GLuint vl::DrawElementsBase::primitiveRestartIndex ( ) const [inline]

Returns the special index which idendifies a primitive restart.

By default it is set to ~0 that is 0xFF, 0xFFFF, 0xFFFFFFFF respectively for ubyte, ushort, uint index types.

void vl::DrawElementsBase::setPrimitiveRestartIndex ( GLuint index ) [inline]

Sets the special index which idendifies a primitive restart.

By default it is set to ~0 that is 0xFF, 0xFFFF, 0xFFFFFFFF respectively for ubyte, ushort, uint index types.

bool vl::DrawElementsBase::primitiveRestartEnabled ( ) const [inline]

Returns whether the primitive-restart functionality is enabled or not.

int vl::DrawElementsBase::instances ( ) const [inline, virtual]

Returns the number of instances for this set of primitives.

Reimplemented from vl::DrawCall.

void vl::DrawElementsBase::setBaseVertex ( int base_vertex ) [inline]

If base_vertx is != 0 glDrawElementsBaseVertex/glDrawElementsInstancedBaseVertex will be used instead of their non *BaseVertx counterparts.

Note that using base_vertx != requires OpenGL 3.2 or higher or ARB_draw_elements_base_vertex. For more information see also http://www.opengl.org/sdk/docs/man3/xhtml/glDrawElementsBaseVertex.xml
