Specular Light: Per Fragment

Fragment Shader Processes Lighting

Swipe to Spin the Cube

The fragment shader calculates lighting. The cube is mapped with a solid color green. Lighting helps define the shape of the cube. Light location, light color, and ambient color are declared with constants to simplify the example.

Vertex Shader Light on a Cube

As the cube spins and moves, both a model matrix and a normal matrix are uploaded. The vertex shader uses the normal attributes and normal matrix to compute lighting per frame. The per vertex specular light shader uses similar functionality, however the vertex shader accomplishes most of the light calculations.

3D Web Design

Educate, inspire and inform with interactive 3D media online. Interactive media in the form of 3D shapes or 3D models, provide unique opportunities to express concepts, such as educational course work or new product features. Seven Thunder Software's simple 3D viewer enables users to see three dimensional objects interactively. Swipe to rotate a model. Tap to select elements on the model. Options allow users to select and learn about individual features.

3D Web Development

Your message can reach the widest audience with 3D Web design. Most 3D programming's implemented with common Web technologies including WebGL, JavaScript, CSS, GLSL and HTML5. 3D Web design with WebGL works on iPhone iOS 8 and up, current Androids, Macintosh computers with OSX Yosemite on up and Windows 10 PCs.

3D Models Online

If a picture's worth a thousand words, then a 3D model's worth ten thousand words! Consider 3D interactive content for education, media and marketing. Seven Thunder Software develops 3D models for the Web, with optimized (fast loading) 3D rendering software, from photographs, blue prints, ideas and real objects.
