Playing with C++11 (using Clang)

August 20, 2012August 21, 2012Ale

I have been following the new C++ standard for quite some time (even before it was named C++11), so I’m very glad to see support for it reaching mainstream compilers…Continue readingPlaying with C++11 (using Clang)

Dynamic Method Injection (in Objective-C)

August 6, 2012August 5, 2012Ale

When asked what I like the most from the Objective-C programming language, I often refer to its dynamic underpinnings. Although Objective-C is a superset of C, the way its designers…Continue readingDynamic Method Injection (in Objective-C)

Light Scattering

February 6, 2012February 7, 2012Ale

When we introduced Programmable Pipeline support to Vortex Engine, we claimed that better visual effects could now be introduced into the renderer. With the introduction of Render-to-Texture functionality into Vortex…Continue readingLight Scattering

Implementing sqrt

January 23, 2012January 22, 2012Ale

I was reading some post about interview questions of 2011 and came across one that stated “find the square root of a number”. Assuming we can’t use the sqrtf function…Continue readingImplementing sqrt

Stencil Shadow Volumes

December 26, 2011January 26, 2012Ale

I’ve built Stencil Shadow Volumes into the Vortex Engine. Shadows are a very interesting feature to implement in an renderer, as they provide important visual cues that help depict the…Continue readingStencil Shadow Volumes

Objective-C Blocks

November 28, 2011November 28, 2011Ale

Lately, I have been playing with Objective-C blocks. These are easy to use constructs that enable defining functions “on the fly” when programming in Objective-C and are very similar to…Continue readingObjective-C Blocks

An Angel with Generated Normals

November 7, 2011November 20, 2011Ale

Sometimes the 3D models we have to display provide no information other than vertex data for the triangles they define. This might be enough to approximate the shape of the…Continue readingAn Angel with Generated Normals

Brief Introduction to Objective-C

November 4, 2011November 20, 2011Ale

Objective-C is a superset of the C programming language that adds object-oriented constructs. Unlike C++, which was influenced by Simula, Objective-C was influenced by Smalltalk, something we can definitely see…Continue readingBrief Introduction to Objective-C
