This is an update on how I’m getting on with Blender. I spent some time reading and viewing tutorials about the Blender interface, and it is unusual in many way. There are dozens and dozens of menus, panel, screens, and many of the buttons are small on my not-so-big screen (see above). That’s not so good for my ageing eyes.
I decided to try some of the tutorials on how to build a simple house, and eventually I ended up with above. A grey house on a grey background in Blender’s 3D view window. I then tried to recreate the above without looking at the tutorial, but before I get into that, I’m going to mention “rendering”.
Rendering is the name of the process for converting the 3D model, whatever it is, into a image that can be used on the web, or as input for further processing using a different program such as the GIMP. It is during this stage that colours and textures get applied. Below is the image resulting from the rendering of the model above. I didn’t do any colouring or apply any textures so it still looks very grey.
As I said I now attempted to draw the house from scratch, not using the tutorial. It took me some time, but eventually I managed to create the model below.
As you can see, I forgot to create the eaves, but apart from that I managed to recreate something like the tutorial model. I should have planned the house properly before I started it. I could correct it in Blender, but it is easier, with such a simple model, to start again.
I’d read or watched a tutorial where materials were applied to a model to, among other things, apply colour to the scene. “Scene” in blender means a single model that can be worked on, such as the houses, backgrounds and lighting in the models above. I decided to render my house, and to colour it in the process, and ended up with the following image. The green area that the house stands on is an object in the scene that I created and coloured, a large flat “mesh”. In Blender your work sort of floats in space, although there is something called “Physics” that I haven’t investigated yet, that may change that.
I continued to familiarise myself with the Blender interface by playing around with house models, and then I decided to try to recreate my UFO from the GIMP in blender. Here it is, in Blender. Unfortunately, the image is quite small.
And here’s a rendered view. I coloured it black and white, so it doesn’t look too impressive and the light levels are a bit low.
I restarted building the UFO, and here’s a screenshot of the second version. This time it should be more visible. It’s view of the mesh that creates the shape of the UFO. Its skeleton, if you like.
And finally for this post, here’s a rendered image of the UFO. AS you can see, it’s a bit chunky, but I’ll be investigating how to smooth it out.
I’m deliberately not going into detail on how I built these images, since they only use the really basic tools, (the UFO is just a squashed sphere for example), and there are many good Blender tutorials on the Internet. If I find some process or facility that I find interesting, I might go into detail, and when I start building a full image, I may post the various steps that got me to the end result.
