Struct luminance::tess::Tess

pub struct Tess { /* fields omitted */ }

GPU tessellation.

GPU tessellations gather several pieces of information:

• Vertices, which define points in space associated with vertex attributes, giving them meaningful data. Those data are then processed by a vertex shader to produce more interesting data down the graphics pipeline.
• Indices, which are used to change the order the vertices are fetched to form primitives (lines, triangles, etc.).
• Primitive mode, the way vertices should be linked together. See Mode for further details.
• And other information used to determine how to render such tessellations.

A Tess doesn’t directly state how to render an object, it just describes its topology and inner construction (i.e. mesh).

Constructing a Tess is not doable directly: you need to use a TessBuilder first.

Methods

impl Tess

pub fn as_slice<V>(&mut self) -> Result<BufferSlice<V>, TessMapError> where
    V: Vertex, 

Obtain a slice over the vertex buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or deinterleaved memory.

pub fn as_slice_mut<V>(&mut self) -> Result<BufferSliceMut<V>, TessMapError> where
    V: Vertex, 

Obtain a mutable slice over the vertex buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or deinterleaved memory.

pub fn as_index_slice<I>(&mut self) -> Result<BufferSlice<I>, TessMapError> where
    I: TessIndex, 

Obtain a slice over the index buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or if no index buffer is available.

pub fn as_index_slice_mut<I>(
    &mut self
) -> Result<BufferSliceMut<I>, TessMapError> where
    I: TessIndex, 

Obtain a mutable slice over the index buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or if no index buffer is available.

pub fn as_inst_slice<V>(&mut self) -> Result<BufferSlice<V>, TessMapError> where
    V: Vertex, 

Obtain a slice over the instance buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or deinterleaved memory.

pub fn as_inst_slice_mut<V>(
    &mut self
) -> Result<BufferSliceMut<V>, TessMapError> where
    V: Vertex, 

Obtain a mutable slice over the instance buffer.

This function fails if you try to obtain a buffer from an attriteless Tess or deinterleaved memory.
