  • Unreal and Reinhard2 tonemapping operators (Tonemapper.Unreal and Tonemapper.Reinhard2, respectively)

  • Material now provides a new set of explicit properties for direct compatibility with glTF (texture properties always take precedence over factor properties):
    • diffuse is now baseColorTexture and baseColorFactor
    • roughnessMetallic is now roughnessMetallicTexture
    • roughness is now roughnessFactor
    • metallic is now metallicFactor
    • emission is now emissionTexture and emissionFactor

  • Texture system redesign. Texture class now can be created from raw pixel data without intermediate SuperImage, hense DDS textures are now loaded directly to Texture object without additional layers of abstraction. Also Texture now supports cubemaps in addition to 2D textures
  • Added support for ASTC texture compression format

  • alphaMode support for glTF materials
• Game
  • New methods: Game.resize, Game.frameTexture

Dagon 0.13.0

• Core
  • State for joystick buttons in EventManager (joystickButtonPressed, joystickButtonUp, joystickButtonDown)
• Rendering
  • Fixed state validation failure on AMD (different sampler types for same sample texture unit). Cubemap and equirectangular environment map now use different texture units
• Assets
  • Images are now loaded using callback mechanism in AssetManager. You can register your own loader function with AssetManager.registerImageLoader method
  • Dagon now uses dlib.image to load images by default. stb_image is available through dagon:stbi extension. Import dagon.ext.stbi module and register the loader with stbiRegister function in your scene constructor:

    stbiRegister(assetManager);
    

  • OBJ loader now supports quads
  • emissiveFactor support for glTF materials
  • Entity.setRotation
• Post-processing
  • Motion blur shader now supports static radial blur - enable it with PostProcRenderer.radialBlurAmount. Fixed Entity.blurMask for objects rendered via forward pipeline. Mask is now used to smoothly decrease motion blur in a processed fragment, which allows to fully avoid undesirable blur leaks inside entities with blurMask property set to 0
  • New properties to control lens distortion effect: PostProcRenderer.lensDistortionDispersion, PostProcRenderer.lensDistortionScale
• Extensions
  • dagon.ext.physics was removed in favour of dagon.ext.newton
  • NewtonRigidBody.addForceAtPos now works correctly. Added NewtonRigidBody.centerOfMass
  • NewtonConvexHullShape is now created from TriangleSet instead of Mesh
  • Fixed compilation of dagon.ext.iqm. Added Actor.blendSpeed property. Switching Actor animation to the same frame range as the current one now doesn't cause loop reset
• Debugging tools
  • Shader programs are now validated against current OpenGL state in debug mode. Invalid shader causes application exit
  • Debug output messages are now more informative, they include textual definitions of message source, type and severity instead of numeric constants. Issues with high severity cause application exit.
• Misc
  • Dagon now uses dlib 1.0.0.

  • NewtonRigidBody.addImpulse
  • NewtonRigidBody.createUpVectorConstraint now returns NewtonJoint pointer.

  • DDS cubemaps support, in 32 and 16-bit RGBA floating-point formats and with pre-baked mipmaps
  • Decoding of generic image formats such as PNG and JPEG now relies on stb_image, resulting in substantial loading speedup for large images. Also PSD and GIF formats are now supported
  • Material now supports roughnessMetallic parameter to pass combined PBR texture. Following glTF convention, G channel stores roughness and B stores metallic
  • Cubemaps now can be created from any image (equirectangular HDR or DDS with mipmaps) using fromImage method
  • Built-in disk shape (dagon.graphics.shapes.ShapeDisk)
• Post-processing
  • Depth of Field effect (dagon.postproc.shader.dof)
  • DeferredRenderer.occlusionBufferDetail parameter that controls resolution coefficient of SSAO buffer
• Extensions
