Yes, the final height map image will be a bitmap file however, to create shapes with crisp edges, I have found it is best to start the process in a vector design environment. Programs such as Adobe Photoshop or GIMP create bitmap images. Start in an image creation program such as Adobe Illustrator or Corel Draw. Here are the steps to create a similar, quality height map. There are very distinct shapes with a precise range of gray values in the image. Here is what the height map used in New Heights looks like: Yes, you can use random colors with blurry, indistinct edges and shapes but the results will also be fairly random too.

Here is how to create a height map with crisp, distinct shapes. The image - the height map - was featureless.
Jorge's tutorial intentionally uses a solid gray map to avoid introducing shapes into the render. If our height map image is a series of darker and darker squares, the result is lower and lower areas in the render.Īny image can be a height map - literally - images with faces or text or anything will work. This sounds complicated at first but here's a visual explanation: The height map is an image in which the color value of the image is used by MB3D to determine what parts of the fractal is higher or lower visually. Make sure the option to 'use a map for the diffuse color' is checked. This is controlled in the lighting window. Maps are typically used in MB3D to add color or texture.

png image that is stored in the map directory of your Mandelbulb3D software installation. This is what the render would look like without the custom height map.Ī height map is any. This image - New Heights - uses a custom height map. This tutorial will walk you through creating a quality custom height map and applying it in a MB3D dIFS render. But what happens if a more complex height map is used? This results in a clean and texture-free bulb form. The height map in Jorge's guide is a uniform, gray image. The tutorial is meant to easily generate the classic bulb shape and it achieves this admirably. Recently my friend Jorge - batjorge - has posted a tutorial on using dIFS with a height map - the HeightMapIFS and the amazingIFS formula. This is not news worthy - MB3D artists have long made use of this technique. This tutorial focuses on creating custom height maps. One of them, dIFS, has the ability to make use of height maps. Mandelbulb3d has several ways to render 3d fractals.
