Public Attributes

unsigned int type_
 GL_FLOAT, GL_UNSIGNED_BYTE, GL_INT, ...
 
unsigned int numElements_
 how many elements of type_
 
VERTEX_USAGE usage_
 position, normal, shader input ..
 
const char * shaderInputName_
 set shader input name, if usage_ = VERTEX_USAGE_USER_DEFINED otherwise this is set automatically, if usage_ != VERTEX_USAGE_USER_DEFINED
 
const void * pointer_
 Offset in bytes to the first occurrence of this element in vertex buffer; Or address to vertex data in system memory.
 
unsigned int divisor_
 For instanced rendering: Step rate describing how many instances are drawn before advancing to the next element. Must be 0 if this element is not per instance data.
 
unsigned int vbo_
 Explicit vbo source of this element, set to 0 if the buffer bound at the time of activating the declaration should be used instead.
