Floating Point operations on different hardware.

!! READ CAREFULLY BEFORE APPLYING !!

There is the same, simple scene rendered in Blender 3D v.2.80 on two different laptops (see attached files: [login to view URL] and [login to view URL])

When you compare these two files - you will see that not every pixel has the same value.

For example, for byte position:

85978: 23 versus 22

86619: 3 versus 4

87261: 252 versus 251

87902: 243 versus 244

90461: 3 versus 2

I need situation, where every pixel has the same value on every hardware.

It probably requires some modifications of Blender source code for FP operations.

Simple scene example - is attached in [login to view URL] python script (remove a cube first from initial Blender scene)

First milestone, as a proof-of-concept ($100) will be:

a compiled Blender version for linux 64-bit, which will produce the same pixels on every platform.

Second milestone:

a static C library, which will render simple scene - and will produce the same pixels on every platform.

Modifications should be proposed via github pull requests on fork of Blender repository.

No offsite communication and/or payments.
