Add a little sphere at the origin #8
Conversation
WalkthroughThe updates across several modules enhance the rendering capabilities and geometry handling for 3D objects, including spheres and cylinders. Key changes involve improving normal vector calculations, expanding sphere initialization parameters, and introducing shaders for enhanced visual effects. These modifications contribute to better memory management, clearer rendering logic, and a more flexible framework for handling multiple types of objects in 3D scenes. Changes

9-10: Consider removing or explaining the commented-out code.The line
// fo_frag_color = fo_color;is commented out. If it's not needed, consider removing it. Otherwise, add a comment explaining its purpose and when it might be used.- // fo_frag_color = fo_color; + // Uncomment to use the input color directly for debugging purposes.
10-10: Clarify the color calculation logic.The color is calculated using the normals and a constant factor. Consider explaining the choice of
0.1and the scaling operation to improve readability and maintainability.// The color is derived from normals, scaled to fit within [0, 1] range. fo_frag_color = vec4(fo_normals.xyz, 0.1) * 0.5 + 0.5;src/foundations/ui/ui_state.zig (1)

24-25: LGTM!The position transformation logic is correct and follows standard practices for vertex shaders.
27-27: Ensure correctness of normal transformation.The normal transformation logic is correct, using the inverse transpose of the transformation matrix. Ensure that
f_transformis always invertible to avoid runtime errors.Verification successful
Normal Transformation Logic is Correct and Matrices are Invertible
The functions
orthographicProjectionandleftHandedXUpToNDCconstruct matrices that are designed to be invertible. The orthographic projection matrix scales by non-zero factors, and the permutation matrix is inherently invertible. Therefore, the use of these matrices in settingf_transformensures it remains invertible, supporting the correctness of the normal transformation logic.Scripts executed
