Detailed Description
Specialized buffer for generative texture/pixel data from TextureNode.
Automatically handles CPU→GPU upload of procedurally generated pixels. Designed for algorithmic image generation: fractals, noise fields, audio visualizations, data mappings, etc.
Philosophy:
- Textures are GENERATED, not loaded from files
- Data flows from algorithm → GPU → screen/shader
- Pixels are just numbers - transform and visualize data freely
Usage: class PerlinNoise : public TextureNode { void compute_frame() override { for (uint32_t y = 0; y < m_height; y++) { for (uint32_t x = 0; x < m_width; x++) { float noise_val = perlin(x, y, m_time); set_pixel(x, y, noise_val, noise_val, noise_val, 1.0f); } } m_time += 0.016f; } };
auto noise = std::make_shared<PerlinNoise>(512, 512); auto buffer = std::make_shared<TextureBindBuffer>(noise);
auto render = std::make_shared<RenderProcessor>(config); buffer->add_processor(render) | Graphics;
