SSAO Advanced-Lighting/SSAO We've briefly touched the topic in the basic lighting chapter: ambient lighting Ambient lighting is a fixed light constant we add to the overall lighting of a scene to simulate the scattering of light In reality light scatters in all kinds of directions with varying intensities so the indirectly lit parts of a scene should also have varying intensities

A Beginner's Guide to Coding Graphics Shaders

Learning to write graphics shaders is learning to leverage the power of the GPU with its thousands of cores all running in parallel It's a kind of programming that requires a different mindset but unlocking its potential is worth the initial trouble

Theory PBR/Theory PBR or more commonly known as physically based rendering is a collection of render techniques that are more or less based on the same underlying theory that more closely matches that of the physical world As physically based rendering aims to mimic light in a physically plausible way it generally looks more realistic compared to our original lighting

Diffuse irradiance PBR/IBL/Diffuse-irradiance IBL or image based lighting is a collection of techniques to light objects not by direct analytical lights as in the previous chapter but by treating the surrounding environment as one big light source This is generally accomplished by manipulating a cubemap environment map (taken from the real world or generated from a 3D

Subsurface scattering

Subsurface scattering (SSS) also known as subsurface light transport (SSLT) is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface at a different point The light will generally penetrate the surface and be reflected a number of times at irregular angles inside the material

How would you implement a classic glowing vectors effect

It seems like GL_LINES GL_POINTS and a full screen blur/bloom would give you a good effect For future reference: if you want really consistent line thickness across platforms you can use triangle strips (or plain triangles) and apply the glow and anti-aliasing in a shader

The idea of learning GLSL first fails because one would also have to learn OpenGL (not bad in itself useful to know both) and rewrite one's program (bad) but there's absolutely nothing wrong with using GLSL material to supplement one's HLSL learning (and vice-versa where relevant) $endgroup$ – Maximus Minimus Jul 24 '12 at 2:55

The MVP matrix used to render the scene from the light's point of view is computed as follows : The Projection matrix is an orthographic matrix which will encompass everything in the axis-aligned box (-10 10) (-10 10) (-10 20) on the X Y and Z axes respectively

HDR Bloom and Tone Mapping

May 19 2007The areas on your screen that bloom are the areas that end up with values higher than 1 after tone mapping not before An example: let's say that i have a very dark scene most values being in the [0-0 1] range but i have a small area that has a 0 2 color After tone mapping this area will end up being very bright and should bloom

OpenGL Graphics and Compute Samples

This sample demonstrates the large performance increase in OpenGL that is made possible by 'Bindless Graphics ' These extensions allow applications to draw large numbers of objects with only a few setup calls rather than a few calls per object thus reducing the driver overhead necessary to render highly populated scenery
