#5144020 Why are my ray traced reflections wrong?

Posted by BloodOrange1981 on 02 April 2014 - 11:20 PM

Ahh, the Normals were in fact fine, but thanks for the suggestion.

 

The problem I has having and why the formula didn`t work was 1) not normalizing the generated ray Direction and 2) in my sphere intersection code I was simply checking for the lowest value of t, and not checking if they were positive values as well, hence shapes behind the ray`s origin influencing the reflected colour. Now it looks an awful lot better!

 

Thank you.

#5128291 Why would devs be opposed to the PS4`s x86 architecture?

Posted by BloodOrange1981 on 02 February 2014 - 07:19 PM

This is more of an open - discussion question as opposed to a straight question-and-answer, if this is inappropriate for this forum please tell me.

In the numerous presentations and interviews regarding the genesis of the Playstation 4 Mark Cerny said he faced some resistance regarding making the PS4`s architecture based on the x86. He had to convince a number of people,including third parties, that it was "suitable for games".

PC game developers have had no choice but use x86 architecture for their games for several generations with spectacular results (despite not having the same kind of low level access to a GPU like you do on consoles) so why would people:

a) need persuading

and

b) what kind of objections would they have?
