Detailed Description
Base interface for all MultiDrawElements* sub classes.
Implements the index-type-independent interface of the class. That is you can cast to MultiDrawElementsBase* and access its members without needing to know whether the actual class is a vl::MultiDrawElementsUInt, vl::MultiDrawElementsUShort or vl::MultiDrawElementsUByte.

| virtual void vl::MultiDrawElementsBase::computePointerVector | ( | ) | [pure virtual] |
Computes the pointer vector to be used when BufferObjects are DISABLED.
Call this function after having updated the count vector and the index buffer indexBuffer().
- Note:
- Normally you don't need to call this function as setCountVector() already calls it.
Implemented in vl::MultiDrawElements< arr_type >, vl::MultiDrawElements< ArrayUInt1 >, vl::MultiDrawElements< ArrayUByte1 >, and vl::MultiDrawElements< ArrayUShort1 >.

Computes the pointer vector to be used when BufferObjects are ENABLED.

- Normally you don't need to call this function as setCountVector() already calls it.
