Release Notes#

This minor release provides several fixes and brings a functionning API to capture the framebuffer and save it as a picture.

Framework integration and source code maintenance#

• Fixed the missing DisableCursor on SDL (by @PMP-P).
• Fixed Linux Golang module build script.

Rendering#

• Added the ability to set the pixel center offset for the projection matrix: SetCameraCenterOffset and GetCameraCenterOffset (by @RobEwbank1).
• Resolved issue #50 (fix CaptureTexture() for Python / Lua)":
  • OLD: uint32_t CaptureTexture(const PipelineResources &resources, const TextureRef &t, Picture &pic)
  • NEW: uint32_t CaptureTexture(bgfx::ViewId &view_id, const PipelineResources &resources, const TextureRef &t, const Texture &readback, Picture &pic)
  • Fixed Picture Set/Get RGBA: GetPixelRGBA and SetPixelRGBA.
  • How does the framebuffer capture work ?
    • In order to grab the framebuffer, create an empty picture: picture = hg.Picture(512, 512, hg.PF_RGBA32)
    • The texture framebuffer is created as in draw to texture
    • Then, set framebuffer to TF_ReadBack: tex_readback = hg.CreateTexture(512, 512, "readback", hg.TF_ReadBack | hg.TF_BlitDestination, hg.TF_RGBA8)
    • When submitting the scene, target the framebuffer: hg.SubmitSceneToPipeline(view_id, scene, hg.IntRect(0, 0, 512, 512), true, pipeline, res, frame_buffer.handle)
    • The capture will be made asynchronously: frame_count_capture, view_id = hg.CaptureTexture(view_id, res, tex_color_ref, tex_readback, picture)
    • Then, only when the current frame counter is greater or equal to frame_count_capture, save the picture: hg.SavePNG(picture, "capture.png")

Misc bug fix#

• Fixed != color operator.
• Brought back the old minmax transform to fix #49.
• Removed warning message (“Invalid node instance”).
• Resolve “Tutorials issues on Linux Ubuntu” (Fixed VertexLayoutPosFloatNormUInt8TexCoord0UInt8).
• Studio related fixes
  • RBT_Static wasn’t saved properly in the scene file.
  • Fixed GetAnimableNodePropertyFloat and SetAnimableNodePropertyFloat to handle the camera FOV.
