HDR Fun

I just picked up a Pentax K-X DSLR because I got my last camera wet on my honeymoon. Oops. Now I have a much nicer camera! I played with it a bit this weeked, and decided to learn a bit about HDR and tonemapping. I made this image with a free program called qtpfsgui (http://qtpfsgui.sourceforge.net/) What an awful software name! But, the software did what I wanted it to do quite nicely. So, my first foray into HDR!

I just created a test with the Blender 2.5 system, animato, and the "Clumping" feature. This video shows the clump factor from -1.0 to 1.0 over a 10 second period. Thus, 5 seconds in has a clump factor of exactly 0. This video had default lighting and default blender material. The only variable is the clumping factor. Maybe it will be of use to somebody looking for the correct clump factor for a model.

A mason jar - a challenge by a friend produced this. I still need to fine tune some of the materials, but the bulk of the work is done.

Rendering Smoke in Blender

Hello all. I stuggled a little bit while trying to figure out Blenders new smoke & volume features and I thought I would write a little guide to make the process easier for others following in my footsteps. I'm righting this tutorial for Blender build 22805 which can be found here. Keep in mind, this proceedure might totally change in the future since this is an early development build of Blender 2.5.

1. Open the build. Start by saving the file so the cache knows where to save. Hit Z to enter wire frame mode.

2. Add a plane to the scene. Scale it down and fit it inside the default cube.

3. Add a particle system to your plane. Set the physics option in particles to "No". On the Render Panel, set the option to "None".

4. Go to the physics tab and add the smoke to the plane.

5. Set the radio button to "flow". Select your particle system in the text box. The default name is "ParticleSystem"

6. Select the default cube and add smoke to it in the physics tab

7. Set the radio button to "domain". You can play with the other options to have fun with your smoke, but it is not necessary.

8. Go to the material tab for the default cube. Select "Volume" from the radio buttons that have - Surface, Wire, Volume, Halo.

9. Under the Shading settings, set Density to 0.

10. Go to the texture tab for the default cube.

11. Under type, select "Voxel Data"

12. On the Voxel Data Panel select "Cube" as your domain object.

13. On the influence panel, check the option "Density".

14. Go to the World Panel and set the horizon color to black to better see the smoke.

15. Hit alt-a to let the simulation run... Cool smoke!

16. Stop the simulation on a cool looking frame.

17. Drag your lamp next to the camera so you get some good front lighting on the smoke.

18. Hit F12 to render and get something like this!

I've been away awhile as my life has gotten quite hectic recently. I just got married on May 1st and then went to the Dominican Republic for the honeymoon. In addition, we just got a new family member, Luna, a Siberian Husky puppy. Needless to say, my time has been quite limited recently.

On to recent graphics stuff I've done!

I just followed an excellent tutorial by Jonathan Williamson and learned a few cool tricks. It was fun watching a quick work flow on a simple project. You can watch the tutorial here:

Just thought I would let you all in on my latest project. A WWII P38. Here is my initial modeling.

Texturing goodness

I followed this tutorial in order to really dig into texturing work. I learned a lot that I will be able to apply to my own images.
