Struct truck_rendimpl::ShapeInstance

pub struct ShapeInstance { /* fields omitted */ }

Instance of shape: Shell and Solid with geometric data.

One can duplicate shapes with different postures and materials that have the same mesh data. To save memory, mesh data on the GPU can be used again.

The duplicated shape by Clone::clone has the same mesh data and descriptor with original, however, its render id is different from the one of original.

Implementations

impl ShapeInstance

pub fn default_vertex_shader() -> ShaderModuleSource<'static>

Returns the default vertex shader module source.

The GLSL original code is src/shaders/polygon.vert.

pub fn default_fragment_shader() -> ShaderModuleSource<'static>

Returns the default fragment shader module source for non-textured polygons.

The GLSL original code is src/shaders/face.frag.

pub fn default_textured_fragment_shader() -> ShaderModuleSource<'static>

Returns the default fragment shader module source for textured polygons.

The GLSL original code is src/shaders/textured-face.frag.
