サンプル

ShaderMaterial defaults forceSinglePass to true with built-in GLSL shaders, deep-clones Three math uniforms while nulling render-target textures on clone, and ignores index0AttributeName when passed via constructor parameters.

よくある思い込み

cloning a ShaderMaterial shallow-copies uniforms and passing index0AttributeName to the constructor assigns it to the material instance

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• ShaderMaterial deep-clones Three math uniforms so mutations to cloned Vector and Color values do not mutate the original material, while resetting render-target textures to null.
• ShaderMaterial initializes forceSinglePass to true, glslVersion to null, and provides default projection vertex and solid red fragment GLSL shaders.
• ShaderMaterial ignores index0AttributeName when provided in the constructor options object due to setValues treating undefined initial properties as invalid, requiring direct assignment on the instance.
• ShaderMaterial.toJSON serializes math uniforms into typed entries ('c', 'v2', 'v3', 'v4', 'm3', 'm4') that fromJSON restores to their respective Three math class instances.
• ShaderMaterial.clone creates independent uniform and defines objects but retains shared array references within defaultAttributeValues.
