WalkthroughThis update introduces several enhancements across multiple modules, focusing on improved rendering capabilities, particularly for geometric objects and shaders. New functions for point reflection, instanced triangles, and handling non-rendering objects are added. Additionally, GLSL shaders are introduced to support advanced visual effects like reflections, enhancing the overall graphical fidelity. These changes create a more flexible and efficient framework for managing rendering operations in the Zig programming environment. Changes

1-11: Verify shader logic and consider improvements.The shader currently outputs a color based on normals. Ensure that the logic aligns with the intended visual effect. Consider adding comments for clarity.
// Calculate and output the reflection color based on normals fo_frag_color = vec4(fo_normals.xyz, 0.1) * 0.5 + 0.5;src/foundations/scenes/plane_distance/reflection_vertex.glsl (1)
1-19: Verify shader logic and consider improvements.The shader applies a reflection transformation and passes attributes to the fragment shader. Ensure that the logic aligns with the intended visual effect. Consider adding comments for clarity.
// Apply reflection transformation and calculate position mat4 f_world_transform = f_reflection_transform; vec4 f_pos = f_mvp * f_world_transform * vec4(f_position.xyz, 1.0); gl_Position = f_pos; // Pass color and normals to fragment shader fo_color = f_color; fo_normals = f_normals;
