AMD will support the Havok Physics Engine

AMD will add the Havok Physics engine to both its multi-core CPUs and GPUs, but AMD managing director noted that the focus is on CPUs given feedback from gaming developers who like the idea of offsetting physics computation to CPU cores.

AMD is hoping to accelerate Havok Physics on both its multi-core CPUs and GPUs and claims that it’s striving to deliver the best of both worlds. However, the main focus at the moment appears to be AMD’s CPUs. AMD and Havok say that they’re planning to optimise the ‘full range of Havok technologies on AMD x86 superscalar processors, and AMD claims that Havok Physics scales extremely well across the entire family of AMD processors.

Havok’s managing director, David O’Meara, explained the priority for CPUs, saying that the feedback that we consistently receive from leading game developers is that core game play simulation should be performed on CPU cores. However, he added that GPU physics acceleration could become a feature in the future, saying that ‘the capabilities of massively parallel products offer technical possibilities for computing certain types of simulation.

Deferred Rendering in Leadwerks Engine

Leadwerks Software has released a paper describing their experience implementing deferred lighting in the OpenGL-based Leadwerks Engine. The paper includes some GLSL code for reconstructing screen space positions without need for a position float buffer, as well as a few results surprising to the author.

Programming Responsiveness

Responsiveness is something that can make or break a game at first impression. This is especially true in reviews where a game with poor responsiveness will be described as being “sluggish”, “unresponsive”, “floaty” or “sloppy”. A better game might be referred to as “tight” or “responsive”. There are several factors that contribute to perceived responsiveness. This article looks at some of them from a programmer’s perspective, and offers some routes to making your game more responsive.

Shader Maker

[English]
Shader Maker is a simple, cross-platform GLSL editor. It works on Windows, Linux, and Mac OS X. It provides the basics of a shader editor, such that students can get started with writing their own shaders as quickly as possible. This includes: syntax highlighting in the GLSL editors; geometry shader editor (as well as vertex and fragment shader editors, of course); interactive editing of the uniform variables; light source parameters; pre-defined simple shapes (e.g., torus et al.) and a simple OBJ loader; and a few more.
