Photo Real versus Photo Raytrace

[robfowler]

I have read the AutoCAD help files relating to photo real and photo raytrace and have played about with both.

The point is that when it comes to the final printed output I can barely see any advantage of rendering using photo real over photo raytraced. The photo real image has a barely discernably better appearance than the raytraced one. But to me the raytraced option renders in minutes as opposed to hours it takes when using the photo real option - especially on more complicated models.

So, in our school, I now advise my pupils to use the raytracing option as it saves so much time.

Anybody else got ideas on this?

Raytrace always, 32bit, 1280 at least.

What stage are your pupils at ?

I have a prelim in 3 weeks and will put DTP, CAD,
Conic Section, Oblique Cone and a M'Perspt in it.

Yes, Raytrace is much faster and I normally set 32 bit and then get the kids to set the image size to user defined (normally fairly big though!).

We have prelims in a week. The AH 3D modelling presentation is just about finished - the models are entirely finished and 3 or 4 presentation drawings done, a couple of them just finalising their scenes. The DTP thematic is kinda dragging its heels - in the middle of thumbnail sketches.

We'll get there - always do!

Whoaaa ! The dtp is dragging ? You are at the thumbnail stage ?
21st of April is SQA deadline :roll: .

I have done the course twice now, and I have just a few visuals to do
and that's it. Modelling just tweaking lighting and SOLDRAWs.

I always make them do just 5 or 6 features all complex source, and then the environment is easier and add mirrors etc.

Started OBlique cones today yeeeeeeuchhhhh ! :twisted: :twisted:

I do DTP Aug-Oct Hols, Modelling After Oct hols - Feb, TG Feb - Prelim Easter - May course revision.

Nick, I have a full set of AutoCAD solutions for Technical Graphics I did for the AH two years ago. The file is 1.4MB. Do you want it or have you already got a copy of the solutions fom another source?
