O3D Post Mortem thoughts

gman — Wed, 22 May 2013 21:11:40 +0000

I don’t remember if there was ever an O3D post mortem but the biggest lesson I took away from it is that if you write a library or some software you have to support it forever. The moment you stop supporting it it dies. (I think PlayN might be another example)

That experience has changed

WebGL 3D – Cameras

gman — Sun, 24 Mar 2013 08:50:39 +0000

This post is a continuation of a series of posts about WebGL. The first started with fundamentals and the previous was about 3D perspective projection. If you haven’t read those please view them first.

In the last post we had to move the F in front of the frustum because the makePerspective fucntion expects

WebGL 3D – Perspective

gman — Thu, 21 Mar 2013 05:00:44 +0000

This post is a continuation of a series of posts about WebGL. The first started with fundamentals and the previous was about 3D Basics. If you haven’t read those please view them first.

In the last post we went over how to do 3D but that 3D didn’t have any perspective. It was using

WebGL Using 2 or More Textures

gman — Tue, 15 Jan 2013 07:25:05 +0000

This article is a continuation of WebGL Image Processing. If you haven’t read that I suggest you start there.

Now might be a good time to answer the question, “How do I use 2 more more textures?”

It’s pretty simple. Let’s go back a few lessons to our first shader that draw a

WebGL: 2D vs 3D Libraries

gman — Sun, 30 Dec 2012 17:56:14 +0000

This post is a kind of side topic on a series of posts about WebGL. The first started with fundamentals

I’m writing this because my claim that WebGL is a 2D API and not a 3D API touches a nerve with some people. I’m not sure why they feel threatened or whatever it is that

WebGL: How It Works

gman — Fri, 14 Sep 2012 03:59:52 +0000

This is a continuation from WebGL Fundamentals. Before we continue I think we need to discuss at a basic level what WebGL and your GPU actually do. There are basically 2 parts to this GPU thing. The first part processes vertices (or streams of data) into clipspace vertices. The second part draws pixels based

WebGL Boilerplate

gman — Fri, 14 Sep 2012 03:47:28 +0000

This is a continuation from WebGL Fundamentals. WebGL sometimes appears complicated to learn because most lessons go over everything all at once. I’ll try to avoid that where possible and break it down into smaller pieces.

One of things that makes WebGL seem complicated is that you have these 2 tiny functions, a vertex

Let’s Debate Coding Style

gman — Sat, 18 Aug 2012 16:32:36 +0000

This might be somewhat of rant but what the hell. Let’s discuss coding style. We each probably have our personal preferences. Tabs, Spaces, 2 spaces, 3 spaces, 4 spaces, tabs set to 4, braces on lines by themselves or not, etc, etc. Until I started working at my present company I’ve never in 25 years

WebGL 3D – Part 1, Orthographic 3D

gman — Sat, 02 Jun 2012 01:50:48 +0000

This post is a continuation of a series of posts about WebGL. The first started with fundamentals and the previous was about 2D matrices. If you haven’t read those please view them first.

In the last post we went over how 2d matrices worked. We talked about translation, rotation, scaling, and even projecting from
