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.
