Detailed Description

Struct that contains all the parameters that Kanzi needs to create a ShaderProgram.

Kanzi loads ShaderProgram::CreateInfo from the kzb file as part of shader creation. You can also use ShaderProgram::CreateInfo to create shaders manually in code.

To define a shader, you must set these fields of the CreateInfo struct:

• Vertex shader code.
• Fragment shader code.
• Binary shader data and format (if applicable).
• Uniform information for each uniform.
• Vertex attribute information for each attribute.
• Render value bindings for uniform data.

Examples

To create a shader whose bindings are in the default state:

    // This example shows how to create a shader whose bindings are in the default state.

    // Specify a simple shader that lights nodes with diffuse lighting and emissive base only.
    const string testFragmentSource(""
        "uniform mediump vec4 Diffuse;\n"
        "uniform mediump vec4 Emissive;\n"
        "uniform mediump vec4 DirectionalLightColor[3];\n"
        "uniform mediump vec3 DirectionalLightDirection[3];\n"
        "varying mediump vec3 vNormal;\n"
        "void main()\n"
        "{"

        "    vec3 nor = normalize(vNormal);\n"
        "    for (int it = 0; it < 3; ++it)\n"
        "    {\n"
        "        float angle = max(dot(nor, normalize(DirectionalLightDirection[it])), 0.0);\n"
        "        color += angle * (DirectionalLightColor[it] * Diffuse);\n"
        "    }\n"
        "    gl_FragColor = Emissive + color;\n"
        "}");

    // Add vertex attribute information.
    createInfo.vertexFormat.emplace_back("kzPosition", VertexAttribute::SemanticPosition, 0u, GraphicsElementTypeFLOAT, 1u, 3u, 0, 0u);
    createInfo.vertexFormat.emplace_back("kzNormal", VertexAttribute::SemanticNormal, 0u, GraphicsElementTypeFLOAT, 1u, 3u, 1, 0u);

    // Add uniforms.
    // First add the uniforms with available fixed operations.

    // Then add the uniforms that are property values.
    createInfo.addUniform(StandardMaterial::DiffuseProperty);
    createInfo.addUniform(StandardMaterial::EmissiveProperty);

    // Light uniforms must declare array size as set in the source.
    createInfo.addUniform("DirectionalLightColor", PropertyDataTypeColor, 3u, AbstractPropertyType(Light::DirectionalLightColorProperty), ShaderProgram::UniformBindingTypeDefault, nullopt, nullptr, ShaderProgram::UniformTransformationPassThrough);
    createInfo.addUniform("DirectionalLightDirection", PropertyDataTypeVector3, 3u, AbstractPropertyType(Light::DirectionalLightDirectionProperty), ShaderProgram::UniformBindingTypeDefault, nullopt, nullptr, ShaderProgram::UniformTransformationPassThrough);

    // Create default bindings for the simple property bindings.
    {
        optional<BindingLoadInfo> info = createDefaultRenderValueBinding(domain, AbstractPropertyType(StandardMaterial::DiffuseProperty), StandardMaterial::DiffuseProperty.getUnqualifiedName(), PropertyDataTypeColor, 1u, ShaderProgram::UniformTransformationPassThrough);
        createInfo.bindings.emplace_back(info->binding, info->targetDataType, info->targetRenderValue);
    }
    {
        optional<BindingLoadInfo> info = createDefaultRenderValueBinding(domain, AbstractPropertyType(StandardMaterial::EmissiveProperty), StandardMaterial::EmissiveProperty.getUnqualifiedName(), PropertyDataTypeColor, 1u, ShaderProgram::UniformTransformationPassThrough);

    ShaderProgramSharedPtr shaderProgram = ShaderProgram::create(domain, createInfo, "Example shader");
    MaterialSharedPtr material = Material::create(domain, "Example material", shaderProgram);

When you want to override binding information, instead of relying on the default states for the bindings, create the bindings manually. To manually create bindings for shaders:

    // This example shows how to create a shader that has some manually specified bindings.

    // Specify a simple shader that lights nodes with diffuse lighting base only.
