WebGL playground

WebGL playground lets you type in your WebGL script and see the results on the same page. The editor lets you work on the JavaScript code and the GLSL vertex/fragment shaders (if you have any) at the same time in a convenient way. Everything is organized, formatted and includes syntax highlighting. You can use arbitrary JavaScript libraries to create your effects, combine multiple fragment and vertex shaders, handle user input, and more.

Google’s ANGLE now OpenGL ES 2.0 conformant, allowing OpenGL ES and WebGL to run on windows

Google announces ANGLE engine passes the rigorous OpenGL ES 2.0 test suite and has been certified as a compliant GL ES 2.0 implementation. Thanks to continued work from Transgaming, in collaboration with Google engineers and other contributors, ANGLE now allows OpenGL ES to be run on Windows without the need for OpenGL drivers. Firefox is already using ANGLE to render WebGL content on Windows. ANGLE is an open-source standalone library. “We hope WebGL developers and implementors will continue to join us in making ANGLE, and the open web platform, successful.” said Vangelis Kokkevis, Software Engineer at Google.

SilverLining 2.3 brings GPU ray-casted 3D clouds to OpenGL developers

Sundog Software released a major update to its SilverLining sky, cloud, and weather rendering SDK that includes substantial performance and visual improvements. SilverLining 2.3 takes full advantage of GLSL fragment shaders in OpenGL 2.x, 3.x, or 4.x to perform real-time ray-casting of volumetric stratocumulus clouds at 100+ frames per second with per-pixel lighting. SilverLining renders real-time skies, clouds, and precipitation for any given time, location, and conditions for OpenGL developers on Windows, MacOS, and Linux. Visit Sundog’s website for screenshots, videos, demos, and an evaluation SDK.

Color-based per-pixel blending of detail textures with GLSL code

This paper describes a method for blending detail textures over terrain. Instead of using masks to define how much each texture to blend into a given fragment of the terrain the color of the base texture is used. A color is assigned to each detail map used, for example some shade of green for grass, a shade of brown for soil, gray for rock and so on. Then, when rendering the terrain, at each output fragment each detail map is blended with a contribution inversely proportional to the ‘distance’ of the base texture color from the color assigned to the detail map in question. This paper comes with GLSL code samples.

Triton Ocean SDK 1.2 Adds Shoreline and Spray Effects using OpenCL and OpenGL

Sundog Software has released a new revision of the Triton Ocean SDK, featuring support for sloping shorelines and particle-based spray effects. Using OpenCL and OpenGL together, tens of thousands of waves with tens of thousands of particles are rendered at hundreds of frames per second. Triton supports flat and geocentric coordinate systems, rendering open ocean and shallow water scenes with ship wakes as well. Triton is compatible with OpenGL 2.x - 4.x, as well as with other technologies. A free demo, evaluation SDK, videos, and images are available on our website.
