You can add HDR bloom post-processing to an SDL GPU project by integrating a Jimenez dual-filter technique that uses a mip chain for progressive downsampling and upsampling to simulate light bleeding.
Jimenez dual-filter bloom is a post-processing technique for HDR rendering that uses a 13-tap downsample with Karis averaging followed by a 9-tap upsample with additive blending to simulate realistic light bleeding.
Yes, a floating-point render target is required for bloom effects. You also need tone mapping and bright HDR values in your scene to achieve optimal visual fidelity and accurate light bleeding.
The best way to make emissive objects glow in SDL GPU is applying a bloom post-processing effect that uses progressive downsampling and upsampling passes to make bright light sources and specular highlights bleed realistically.
Bloom effects look wrong without tone mapping because the post-processing pipeline requires tone mapping alongside a floating-point render target and bright HDR scene values to correctly evaluate and blend the light bleeding.
This bloom effect is designed for HDR rendering capabilities. Using it with standard non-HDR rendering lacks the bright HDR values and floating-point precision required for the Jimenez dual-filter pipeline to produce optimal results.
