CONTEXT

• Allow node removal
• Some mechanism to allow scaling - e.g. scale before blurring, rescale and blend like suggested Deus Ex: Human Revolution - Graphics Study
• Expose a mechanism to allow samplers
• Support Multi-pass shaders
• Investigate cereal for serialization and deserialization
• Migrate from JsonTree to JsonCpp for serialization
• Load a context from JSON
• Tile when texture size exceeds GL_MAX_TEXTURE_SIZE
• Use GL_NV_texture_barrier for texture-internal ping-pong'ing
• Investigate the Boost Graph Library
• Investigate graph algorithms in bss-util to improve the dependency solver

NODE

• Pull shader stuff out of Effector node to allow for shader-based generators
• Validate value type in Node::setValueForInputPortKey
• If not using ci::gl::GlslProg, consider using GL_ARB_separate_shader_objects on 4.1+. Also see One Year of Porting and A bit of perspective on OpenGL 4.1 separate programs

NODES

• Rename mixAmount to intensity
• Create a simple shader-based solid color generator node
• Compile vibrance node with preprocessed curve instead of using a uniform
• Colorspace conversion nodes! YCoCg/CIELAB/HUSL/RGB/sRGB
• Source node classes: FBOImage, RTT?
• FXAA node like triton

ISF NODE

• Support the event input type
• Support multiple render passes, "PASSES"
• Support persistent render buffers, "PERSISTENT_BUFFERS"
• Support static image resources "IMPORTED"

GENERAL

• Use CI_ASSERT places that make sense
• Make a pass as using const and mutable where appropriate
• Include a sample application
• Profile with Cinder-Profiler and Remotery
• Sprinkle in some glGetError use?
• Think about optimizations by reducing binds
