Remarks
Class responsible for holding specifications for Mesh creations. This class generates a MeshSpecification via the MeshSpecification#make(Attribute[], int, Varying[], String, String) method, where multiple parameters to set up the mesh are supplied, including attributes, vertex stride, Varying, and vertex/fragment shaders. There are also additional methods to provide an optional ColorSpace as well as an alpha type.
For example a vertex shader that leverages a Varying may look like the following:
Varyings main(const Attributes attributes) {
Varyings varyings;
varyings.position = attributes.position;
return varyings;
}
The corresponding fragment shader that may consume the varying look like the following:
float2 main(const Varyings varyings, out float4 color) {
color = vec4(1.0, 0.0, 0.0, 1.0);
return varyings.position;
}
The color returned from this fragment shader is blended with the other parameters that are configured on the Paint object (ex. Paint#setBlendMode(BlendMode) used to draw the mesh.
The position returned in the fragment shader can be consumed by any following fragment shaders in the shader chain.
See https://developer.android.com/develop/ui/views/graphics/agsl for more information regarding Android Graphics Shader Language.
Note that there are several limitations on various mesh specifications: 1. The max amount of attributes allowed is 8. 2. The offset alignment length is 4 bytes. 2. The max stride length is 1024. 3. The max amount of varyings is 6.
These should be kept in mind when generating a mesh specification, as exceeding them will lead to errors.
