Highlights

• Migrating from ADA to VERA framework which incorporates lot of geometry operations from HILMA on top of a new app API similar to P5js.
• Adding Geometry buffers for deferred rending, and screenspace techniques such us SSAO, SSR and Volumetric Scattering Lights through LYGIA

• lot of tinny fixes in preparation for the Shader Prototyping Workshop

Full Changelog: https://github.com/patriciogonzalezvivo/glslViewer/compare/2.1.2...2.2.0

• Skip light shadow map when is not call in the shader as u_lightShadowMap;
• Add doubleBuffers (as u_doubleBuffer[NUMBER] branched by DOUBLE_BUFFER_[NUMBER])
• Half/Float precision FBO on WASM
• Fixed size buffers by comments. Ex: uniform sampler2D u_buffer0; // 512x512
• Adding uniform bool u_cameraChange to flag when camera change position
• Continuous zoom, drag for 3D scenes
• Adding doubleBuffers examples
• Improving GPGPU simulations examples

• Major rearch. Splitting framework into ADA library. Which internally compiles GLFW and other GL dependencies
• Change to use CMake for consistency across platforms
• Cross compilation to WASM using emscripten
• Binnary PLYs, OSC, Audio Textures and Video are now optative features
• Using Liblo for OSC to have 6 digits precision after the floating point

Special thanks to:

• @sp-bertrand-carre and @mihaisebea-gl for ironing out the windows compilation
• @bespsm for cleaning the memory management of stream textures and introducing Audio textures
• @ben-hansske and @anncxx for multi-thread frame recording
• @ak-1 for improving the mouse behaviour

• Support for LST files
• Support for Binnary PLY
• Support for more image formats: psd, tga, bmp and gif
• Blend modes: ADD / ALPHA / MULTIPLY/ SCREEN / etc
• Screensaver mode
• Better examples
• Bug fixes

A lot of new things but the biggest one are

• Support for OBJ materials
• Support for GLTF files
• Default PBR shader
• OSC support
• Windows compile rutines

Adding:

• Computation of tangents pre scene loading
• Computation of Spherical Harmonics when cubemap is provided and pass as a uniform array u_SH also flags "CUBE_MAP" and "SH_ARRAY" #defines
• Adding light object that can be control from console commands and feed uniforms: u_light and u_lightColor
• Adding camera parameters that can be control from console commands and feed uniforms: u_camera, u_cameraAperture, u_cameraDistance, u_cameraEv100,u_cameraExposure,u_cameraFarClip,u_cameraNearClip,u_cameraSensitivity, u_cameraShutterSpeed
• useful #defines of model attributes: "MODEL_HAS_COLORS", "MODEL_HAS_TEXCOORDS", "MODEL_HAS_NORMALS" and "MODEL_HAS_TANGENTS"
• adding culling,[none|back|front|both] console command
• adding debug,[on|off] visual references for model bounding box and light position through console command
• adding u_scene_depth for depth map of the scene

New features:

• Multiple buffers using BUFFER_[N] #define flags
• Cubemaps using -c cubemap.png
• Support for .hdr textures and cubemaps
• Watch for changes on dependency files
• Save image secuence from console command
• #ifdef BACKGROUND and #ifdef POSTPROCESSING define flags to brach subshaders for the background and a last post-processing pass ( the scene renders to uniform sampler2D u_scene;).
• Improved console interface:
  • // > hint
  • help prints all commands
  • uniforms, buffers, textures, files, defines, frag_dependencies, vert_dependencies debug commands
  • camera_distance , camera_position get and setters
  • sequence,[from_sec],[to_sec]
  • define,[KEYWORD]/undefine,[KEYWORD]

• Adding frag/vert console commands to print fragment/vertex source code
• Adding -v/--verbose arguments
• changing --help argument output
• Changing -m argument for -c/--cursor
• Compilation time now only shows on -v/--verbose mode
• COUTs print w '//' at the beginning in case someone wants to use the output directly as source code

• Adding --help argument

• Adding console gcc-like precompiler arguments to satisfy GLSL shaders dependencies -I[dir] -D[define]

• Adding 'screenshot' command on CIN to save screenshots to other files rather than the specified on -o [file]

• Adding travis and editorconfig files to help others contribute

• General housekeeping of utils functions. Now they are split in tools/fs tools/text and tools/geom

• Better Makefile: Using Broadcom SDK when is possible not... only on Raspberry Pi
• Upgrading GLM to v0.9.8.4
• Upgrading stb_image.h to v2.14
• Upgrading stb_image_write.h to v1.03

• console outs for time, delta and fps on demand

Adding:

• Adding Debian packages files

• Adding #defines on shader for platforms (RaspberryPi's GPU driver have to many discrepancies) https://github.com/patriciogonzalezvivo/glslViewer/commit/419778b6236ed1aab3b5898fd5438300d8bc7d75

Suport for platforms:
Linux Ubuntu, Linux Raspbian, Darwin OSX

• Support for obj/ply geometries
• Support for textures
• Backbuffer pingpong
• glslLoader script to download and run log examples under http://thebookofshaders.com/log
