This release brings a new deferred rendering pipeline with support for unlimited number of shadow-casting lights. All light types, including point lights, can now cast shadows. Please note that the deferred renderer has specific hardware requirements and therefore it is not supported on all platforms! When deferred rendering is not available, you can still use the old default renderer, but that is still limited to maximum 8 punctual lights and only a single shadow-casting light. Additionally, you can now configure frame skip for capturing shadowmaps or mark a light as "static" to capture its shadowmap only once to increase performance.

Changelog:

  • Added new struct BBMOD_DeferredRenderer, which is a deferred renderer with support for unlimited number of shadow-casting lights.
  • Added new function bbmod_deferred_renderer_is_supported, which checks whether deferred renderer is supported on the current platform.
  • Added new macro BBMOD_SHADER_GBUFFER, which is a shader for rendering models into the G-buffer.
  • Added new macro BBMOD_MATERIAL_DEFERRED, which is an opaque material that can be used with the new BBMOD_DeferredRenderer.
  • Added new macro BBMOD_SHADER_TERRAIN_GBUFFER, which is a shader for rendering terrain into the G-buffer. Supports 3 terrain layers at most!
  • Added new macro BBMOD_MATERIAL_TERRAIN_DEFERRED, which is a terrain material that can be used with the new BBMOD_DeferredRenderer.
  • Moved properties EnableSSAO, SSAOScale, SSAORadius, SSAOPower, SSAOAngleBias, SSAODepthRange, SSAOSelfOcclusionBias and SSAOBlurDepthRange from BBMOD_DefaultRenderer to BBMOD_BaseRenderer.
  • BBMOD_PointLight can now also cast shadows.
  • Added new property Frameskip to BBMOD_Light, which is the number of frames to skip between individual updates of the light's shadowmap.
  • Added new property Static to BBMOD_Light, which when set to true, the light's shadowmap is captured only once.
  • Added new property NeedsUpdate to BBMOD_Light, which if true, then the light's shadowmap needs to be updated.
  • Added new member Background to enum BBMOD_ERenderPass, which is a render pass for background objects (e.g. skydome).
  • Material BBMOD_MATERIAL_SKY now uses the Background render pass instead of Forward.
  • Implemented the new Background render pass into BBMOD_DefaultRenderer.
  • Added new macro BBMOD_U_SHADOWMAP_NORMAL_OFFSET_VS, which is the name of a vertex shader uniform of type float that holds how much are vertices offset by their normal before they are transformed into shadowmap-space, using formula vertex + normal * normalOffset.
  • Added new macro BBMOD_U_SHADOWMAP_NORMAL_OFFSET_PS, which is the name of a fragment shader uniform of type float that holds how much are vertices offset by their normal before they are transformed into shadowmap-space, using formula vertex + normal * normalOffset.
  • Macro BBMOD_U_SHADOWMAP_NORMAL_OFFSET is now obsolete! Please use the new BBMOD_U_SHADOWMAP_NORMAL_OFFSET_VS instead.
  • Added new function bbmod_hdr_is_supported, which checks whether high dynamic range (HDR) rendering is supported on the current platform.
  • Added new macro BBMOD_U_HDR, which is the name of a fragment shader uniform of type float that holds whether HDR rendering is enabled (1.0) or not (0.0).
