2. GL_NV_vertex_buffer_unified_memory

####A video card that supports these extensions

1. GL_ARB_separate_shader_objects
2. GL_ARB_timer_query
3. GL_ARB_debug_output
4. GL_ARB_draw_indirect
5. GL_ARB_base_instance
6. GL_ARB_shader_atomic_counters
7. GL_ARB_clear_buffer_object
8. GL_ARB_buffer_storage
9. GL_ARB_map_buffer_range

####Dependencies

1. GLEW
2. GLFW
3. GLM

###How to build GLEW:

Grab GLEW

• git clone [email protected]:nigels-com/glew.git
• git checkout tags/glew-2.2.0 -b ogl_experiments

Why not install glew through package manager?

####Unix:

• make extensions (to generate src/glew.c GLEW)
• make
• sudo -s
• make install
• make clean

####Windows:

• use the project file in build/vc6/

###How to build GLFW:

Grab GLFW

• git clone [email protected]:glfw/glfw.git
• git checkout tags/3.3.8 -b ogl_experiments

####Unix:

• cmake .
• make

####Windows:

• Link a new project to the make file

###Experiments

####bindless_nv

Compares bindless vbo's vrs traditional vbos

####indirect

Learning experiment on how to work with indirect rendering

####depth_buffer

Comparing traditional vs logrithmic writes to the depth buffer

####round_trip

Finding the amount of time it takes to send a texture to the gpu, write to it and then read it back

####raster_pattern

Renders GPU's rasterization pattern

####bits

Messing around with bit twiddling for the paper "Single Pass GPU Voxelization" section 6.

####scene_depth

Gets the used depth of the scene in a single draw call.

####single_pass_voxel

Implementing the paper "Single-Pass GPU Solid Voxelization for Real-Time Applications".

####glsl_derivative

A test to see if dFdx(position) and dFdy(position) are orthogonal

####wire_aa

Tests wether a proj matrix needs to be transposed for dot product ops, and finds pixel sizes at different depths.

####ogl_compute

Demo project to experiment with opengl compute shaders. Renders out a 2D fluid simulation.

####buffer_streaming

App to compare different buffer streaming techniques.
