Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string. The set of APIs used to compile, link, and pass parameters to GLSL programs are specified in three OpenGL extensions, and became part of core OpenGL as of OpenGL Version 2.0.
The first Counter-Strike surf map was created in 2004 after Joyce, who had created a custom map called "Killbox" (ka_killbox), began to slide off the roof of a house and was able to jump to safety. Realizing this would be fun in and of itself, he began to create a new map solely dedicated to surfing, "The Gap" (surf_the-gap).
Newer geometry shaders can generate new vertices from within the shader. Tessellation shaders are the newest 3D shaders; they act on batches of vertices all at once to add detail—such as subdividing a model into smaller groups of triangles or other primitives at runtime, to improve things like curves and bumps, or change other attributes.
The unified shader model uses the same hardware resources for both vertex and fragment processing. In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities.
Light source shaders compute the color of light emitted from a point on a light source to a point on a target surface. Surface shaders model the color and position of points on an object's surface, based on incoming light and the object's physical properties. Displacement shaders manipulate surface geometry independent of color.
It can also be exacerbated by high ISO settings, which increase the camera's sensitivity to light and can result in more charge accumulation. While the bloom effect can be distracting in some images, it can also be used creatively to add a dreamy or otherworldly quality to photos.
Drawing the scene with shadows can be done in several different ways. If programmable shaders are available, the depth map test may be performed by a fragment shader which simply draws the object in shadow or lighted depending on the result, drawing the scene in a single pass (after an initial earlier pass to generate the shadow map).
"Dust II", also known by its filename de_dust2, is a video game map featured in the first-person shooter series Counter-Strike. Dust II is the successor to "Dust", another Counter-Strike map, and was developed by David Johnston before the official release of the original Counter-Strike game.
