Macro Texture

Description
Creates a 3D image from an 8 bit (256 color) BMP image.
In other words, it allows one to build a 3D project very easily from a bitmap image using grayscale (256 shades of gray).
If one 32 bit BMP image is selected, the image is represented in points.
The FCCreaLoft Macro Loft macro is used to automate the multi loft operation.

FCCreaLoft Macro Loft

Description

This small macro allows one to build a 3D project very easily from a bitmap image with 256 shades of gray.

I hope that this macro will revolutionize the way we think when modeling with CAD and CNC converting to 3D objects with little to no intervention.

Everything becomes possible regardless of the complexity of the image!

The FCCreaLoft Macro Loft is used to automate the multi loft operation.

Usage

This macro requires an image in 256 shades of gray (0-255) therefore before executing the macro, convert your image into grayscale (black and white). When running the macro, the number of colors is detected automatically. Note: if the image is more than 256 colors another function is expected (WIP). Each color (gray level) is regarded as a deep, white (255) the level high and black (0) the lowest level (deep).

Configuration is done before the opening of the file, default values are the settings provided to get a project's dimensions:

The image file unfolds like a scanner x1 x2 x3 ... in 1 mm increments in FreeCAD similarly to the value y of 1 mm at a time. The value of z is given by the value of the color. These values are configurable in the macro.

Important note: depending on the size of the image, the project can become very large in size! For example, a simple image of (100px x 100px) width/height would be: 100 x 100 = 10000 points. Each of the 10,000 points corresponds to a coordinate, so that means 10000 X, 10000 Y, and 10000 Z coordinates in actuality.
