class VBO(object) |
| |
Instances can be passed into array-handling routines
You can check for whether VBOs are supported by accessing the implementation
attribute of the VBO, which will raise a RuntimeError if there is no available
implementation.
Attributes:
int copied -- whether we are copied to back-end yet
int created -- whether we've created a buffer yet
unsigned int buffer -- our buffer once created
object data -- our data-holding array-compatible object
target -- our resolved GL constant target
target_spec -- our (unresolved) GL constant specifier
usage -- our resolved GL constant usage
usage_spec -- our (unresolved) GL constant usage specifier
_copy_segments -- slices of data to copy to back-end
_I_ -- our implementation object
arrayType -- our reference to arraydatatype.ArrayDatatype

class VBOOffset(object) |
| |
Offset into a VBO instance
This is just a convenience object that lets you say
vbo + integer and have the value passed as the correct
data-type instead of being interpreted as a pointer to
an integer-array of the offset.
