Blender Cycles Texture Nodes How-to

Posted by Dennis in 3D, Blender No comments

Blender’s current internal renderer is quite old and is being updated with a modern renderer called Cycles. It is included in the current version but you have to manually select it. It’s still in its early stages and still has a limited feature set. The results are already very promising though. They look much more [...]

Rajawali Tutorial 4: Optimisation

Posted by Dennis in 3D, Android, Rajawali 2 comments

The onSurfaceCreated() method in the Renderer is called every time the rendering starts or whenever the context is lost. This typically happens when the orientation changes or when the device wakes up after going to sleep. When the context is lost, all the textures are deleted from memory. This is not something Rajawali inflicts upon [...]

Rajawali Tutorial 2: Creating a live wallpaper and importing a model

Posted by Dennis in 3D, Android, Rajawali 17 comments

I’m going to be lazy and make you download the zipped Eclipse project. Get it here. The basics of Android live wallpapers are well documented so I won’t go over that. I suggest you take a look at AndroidManifest.xml, /res/xml/preferencescreen.xml, /res/xml/settings.xml and com.rajawali.tutorials.WallpaperSettings for wallpaper specific stuff. Here are the specifics for Rajawali. The RajawaliTutorial2Wallpaper [...]

Announcing Rajawali: An OpenGL ES 2.0 Based 3D Framework For Android

Posted by Dennis in 3D, Android, Rajawali 8 comments

I’ve been working on this on and off for the last couple of months. It is by no means a fully-featured 3D engine. It has some nice features and I figured I might as well move it to a public repository so other people can use it as well. The other 3D engine for Android [...]

Min3D for Android: Using The Accelerometer To Control The Camera

Posted by Dennis in 3D, Android 14 comments

NOTE: This OpenGL ES 1.1 framework isn’t maintained anymore. Check out the OpenGL ES 2.0 Rajawali framework which also supports live wallpapers. I haven’t done anything with Min3D for while. I know people have logged some bugs on Google Code but I haven’t had the time to look at them yet. Shame on me. Seeing the [...]

OpenSceneGraph Level of Detail Management

Posted by Dennis in 3D 1 comment

I managed to get my head around the basics of OpenSceneGraph by reviewing the book OpenSceneGraph 3.0 Beginner’s Guide. I picked up a few things that were very interesting. OSG has a very convenient way of using an optimisation technique called Level of Detail management. Simply said: when an object is far away from the [...]

Book Review: OpenSceneGraph 3.0 Beginner’s Guide

Posted by Dennis in 3D 1 comment

Packt Publishing sent me this OpenSceneGraph 3.0 beginner’s guide for review. I have worked with 3D engines like Irrlicht and Ogre but I never had the chance to properly look at OpenSceneGraph. The latter is apparently used a lot in scientific visualisation & simulation while Irrlicht and Ogre are mostly used for games & entertainment. [...]

The gotoAndSki(“Switzerland”) conference

Posted by Dennis in 3D, Kinect, Speaking 1 comment

Disclaimer: I’ve kept the session descriptions short. I recommend keeping an eye on the video site on which the session videos will be published. The rural village of Stechelberg in Switzerland was the setting of the second edition of the gotoAndSki() conference. Skiing in the Alps is always a great experience and combining this with [...]
