impl Drawing

pub const fn new() -> Drawing

pub fn load(&mut self, library: &OpenGraphicsLibrary)

Available on Windows only.

impl Drawing

pub unsafe fn draw_arrays(&self, start: i32, count: i32, mode: PrimitiveType)

Renders primitives from array data.

GLError::InvalidValue is generated if count is negative.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array and the buffer object’s data store is currently mapped, or if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.

pub unsafe fn draw_elements( &self, start: i32, count: i32, index_type: IndexType, mode: PrimitiveType, )

Render primitives from array data.

GLError::InvalidValue is generated if count is negative.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object’s data store is currently mapped, or if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.

pub unsafe fn draw_elements_typed<T: AvailableIndexType>( &self, start: i32, count: i32, mode: PrimitiveType, )

Renders primitives from array data.

GLError::InvalidValue is generated if count is negative.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object’s data store is currently mapped, or if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.

pub unsafe fn multi_draw_arrays( &self, start: &[i32], count: &[i32], mode: PrimitiveType, )

Renders multiple sets of primitives from array data.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array and the buffer object’s data store is currently mapped.

pub unsafe fn multi_draw_elements( &self, start: &[isize], count: &[i32], index_type: IndexType, mode: PrimitiveType, )

Renders multiple sets of primitives by specifying indices of array data elements.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object’s data store is currently mapped.

pub unsafe fn multi_draw_elements_typed<T: AvailableIndexType>( &self, start: &[isize], count: &[i32], mode: PrimitiveType, )

Renders multiple sets of primitives by specifying indices of array data elements.

GLError::InvalidOperation is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object’s data store is currently mapped.
