Samples

Starter (G3D10/samples/starter)
	A good starting point for building your own G3D programs. Has subdirectory structure, a journal, a Windows resource file, and standalone solution files. Just copy everything from samplers/starter to your own directory and rename starter.sln. Do not rename main.*. To aid in discovering methods, the sample App class overrides most G3D::GApp event handling methods. You do not have to do this... the default GApp::onGraphics3D, GApp::onPose, and other methods are fine for most programs. (This is the program that iCompile creates for you in an empty directory on Linux and MacOS.) G3D::GApp G3D::Scene G3D::Entity G3D::ArticulatedModel G3D::LightingEnvironment G3D::Draw G3D::DepthOfField G3D::MotionBlur G3D::AmbientOcclusion
VR Starter (G3D10/samples/vrstarter)
	A good starting point for VR applications. Optimized to provide performance for VR rendering and based on the G3D::VRApp base class, which extends G3D::GApp with some VR-specific elements. Built-in teleportation, elevation adjustment for the player, and support for pluggable gaze-tracking solutions. Automatically falls back to emulating a HMD and gaze tracker if physical ones are not present. G3D::VRApp
Tiny Starter (G3D10/samples/tinyStarter)
	Like starter, but without the directory structure, scene loading, journal, and default event handler method overrides. If you're making a small prgram and want the minimal GApp subclass, this is a good place to start. G3D::GApp G3D::Draw
Viewer (G3D10/tools/viewer)
	Loads most data files supported by G3D, including, OBJ, FBX, 3DS, STL, IFS, GTM, MP4, PNG, JPG, FNT, ArticulatedModel.Any, UniversalMaterial.Any, and displays them in an appropriate manner. Use this for previewing objects, discovering font characters, and debugging data files.
All Stages Shader (G3D10/samples/allStagesShader)
	Shows domain (tessellation), hull, vertex, geometry, and fragment (pixel) shaders. While these are fully supported both by G3D and OpenGL, in practice most developers are migrating to either vertex + pixel or mesh + pixel shaders as the other stages have not proved a good fit for most GPU algorithms. G3D::Shader Tessellation, hull, geometry, vertex, and pixel shader
CPU Real Time Ray Trace (G3D10/samples/cpuRealTimeRayTrace)
	Program that shades ray hits on the CPU. The actual ray-triangle intersection will be CPU or GPU depending on your graphics card and processor. Ray tracing CPU rendering G3D::TriTree G3D::UniversalBSDF G3D::GuiRadioButton G3D::GuiNumberBox G3D::GuiButton
Deep G-Buffer Radiosity (G3D10/samples/deepGbufferRadiosity)
	Screen space effects Complex GUI development G3D::GBuffer Splitscreen rendering
Entity (G3D10/samples/entity)
	A spaceship flying video game demonstrating how to mix procedural and data-driven Entity construction. G3D::VisibleEntity Interactive control G3D::AudioDevice Procedural scene creation
Geometry Shader (G3D10/samples/geometry)
	OpenGL 3.x / GLSL 3.3 G3D::Shader
Image Processing (G3D10/samples/imageProcessing)
	A good starting point for 2D image operations in G3D, where the input and output tend to be in Textures and most passes are fullscreen. G3D::Shader G3D::Args::setRect G3D::RenderDevice::push2D G3D::Texture G3D::Framebuffer 2D rendering with no 3D Convolution
Implict Planet Shader (G3D10/samples/implicitPlanet)
	A "shadertoy"-style implicit surface with multiple passes for different effects at different resolutions. Demonstrates render-to-texture as well as advanced shader techniques. G3D::Shader G3D::Texture G3D::Framebuffer
Maximum Performance (G3D10/samples/maxPerf)
Image coming soon–example under construction!	A stripped down rendering loop designed for near-minimal latency and near-peak throughput. This has simple graphics and is intended for display measurements in research when measuring the upper bound ("speed of light") performance for graphics. The approach taken here would not scale for complex graphics and interaction, where the usual G3D::Scene and G3D::Surface infrastructure performs high-level optimizations but incurs some fixed overhead. G3D::Shader G3D::VertexBuffer G3D::AttributeArray
Minimal OpenGL (G3D10/samples/minimalOpenGL)
	An example of using OpenGL without most of G3D's abstractions. This is intended for teaching OpenGL and creating minimal bug reports for graphics card vendors. It makes a clear case for why it is usually much more efficient for both the programmer and the computer to build applications on a higher-level engine. Raw OpenGL initialization and implementation Raw OpenVR initialization and implementation Procedural texturing Direct use of uniform interface blocks Direct use of textures and framebuffers
Multiple Views (G3D10/samples/multiview)
	Rendering to multiple viewports to create a CAD-like application G3D::RenderDevice::setViewport G3D::Surface::renderWireframe G3D::GuiWindow G3D::IconSet G3D::Draw md
Net Chat (G3D10/samples/netChat)
	G3D::NetConnection G3D::GuiWindow
Path Tracer (G3D10/samples/pathTracer)
	Provides a GUI for non-realtime rendering with the built-in PathTracer class. Automatically GPU accelerated on NVIDIA graphics cards via OptiXTriTree. G3D::PathTracer G3D::Film
Pixel Shader (G3D10/samples/pixelShader)
	G3D::Shader G3D::ThirdPersonManipulator G3D::GuiDropDownList G3D::GuiSlider
Primary Ray Trace (G3D10/samples/primaryRayTrace)
	Using G3D::TriTree to cast arbitrary rays. This technique is useful for light field and VR displays as well as tracing reflection probes. This example shows a fisheye projection with full GPU shading. G3D::TriTree G3D::Surfel Deferred shading
