Bug 1021: Add OculusVR distortion renderer (single FBO and dual FBO); Add GLEventListener2 (WIP); Refine FloatUtil
- GLEventListener2 extends GLEventListener adds refined control:
- display w/ flags, i.e. repeat, don't clear
- setProjectionModelview(..)
- FloatUtil.* Add return value for chaining, where missing
+++
- jogamp.opengl.oculusvr.OVRDistortion
- Handles all OVR related data and maps it to shader + GL buffers
- display method
- com.jogamp.opengl.oculusvr.OVRSBSRendererSingleFBO implements GLEventListener
- Simple OVRDistortion renderer using single FBO
- Using upstream GLEventListener2 (the content)
- com.jogamp.opengl.oculusvr.OVRSBSRendererDualFBO implements GLEventListener
- Simple OVRDistortion renderer using two FBOs
- Using upstream GLEventListener2 (the content)
