Detailed Description

Description: ON_DepthImageShader is used to pass a shader function and context to ON_DepthImage drawing tools.

DefaultShadePixel()

static bool ON_DepthImageTriangleShader::DefaultShadePixel ( void *  context, const class ON_DepthImageTriangle *  triangle, ON__UINT_PTR  id, double  depth, const class ON_DepthImagePixel *  pixel  )

static

Description: When m_context points to a ON_DepthImageDefaultShaderContext class, the DefaultShadePixel function can be used as the m_shade_pixel_function.

DefaultTestTriangle()

static bool ON_DepthImageTriangleShader::DefaultTestTriangle ( void *  context, const class ON_DepthImageTriangle *  triangle  )

static

Description: When m_context points to a ON_DepthImageDefaultShaderContext class, the DefaultTestTriangle function can be used as the m_test_triangle_function. Parameters: context - [in] This must point to a ON_DepthImageDefaultShaderContext class. triangle - [in] Triangle information about the triangle ON_DepthImage::DrawTriangleMesh() will draw if this function returns true. Returns: 0 == (triangle->m_triangle_status & ON_DepthImageDefaultShaderContext::m_test_triangle_status). Example: To create a triangle shader that will cull back faces: ON_DepthImageDefaultShaderContext shader_context; shader_context.m_test_triangle_status = ON_DepthImage::back_triangle; ON_DepthImageTriangleShader shader(ON_DepthImageTriangleShader::Default); shader.m_context =
