• How do I integrate a BSDF into a ray caster.

  - by pelb

  I'm trying to implement sub surface scattering at isosurfaces and looked up how a BSDF works mathematically. Implementing the reflective and diffuse part seems to be quite easy as i just have to evaluate phong at the isosurface intersection, but how do you I apply the transmissive part of the BSDF? In what way do i have to modify the ray direction. Any pointers to a practical implementation are welcome. Thanks and So long!

• How many registers in custom VM?

  - by DeadMG

  I'm designing a custom VM and am curious about how many registers I should use. Initially, I had 255, but I'm a little concerned about backing 255 pointers (a whole KB) on to the stack or heap every time I call a function, when most of them won't even be used. How many registers should I use?

• Basic framework for presentations using HTML5 + javascript

  - by Brian C

  Do you know a framework for making presentations using only HTML5 and javascript technologies? I'm not talking about "export" features of various presentation software (powerpoint or OOo presentation). Some requirements for the presentations made with this "framework": take advantage of the latest HTML5 features (audio, video, canvas?) same with CSS3 (font support, gradient, shadows, transitions and transformations) If there's no such thing, example of good presentations or pointers on the subject would be appreciated.

• Silverlight 4: Any touch library that supports gestures & touch events?

  - by funwithcoding

  Silverlight provides only Touch.FrameReported event and doesnt provide any events for the UIElements like it does for mouse events(ex: MouseDown, MouseUp).

Any pointers will be appreciated.

• Line for signature in markdown

  - by JBarberU

  I'm writing a document using markdown, which I'm exporting to a PDF using pandoc. At the end of the document I need to have space for signatures on a printed copy of the PDF. I've tried to find how to draw a line with a fixed width, but so far I only got to escaping the underscore character, which doesn't feel quite right. It's as if I'm missing something, this couldn't possibly be that unusual to want to do. Any help or pointers are greatly appreciated.

• JPA CascadeType.ALL does not delete orphans.

  - by Paul Whelan

  I am having trouble deleting orphan nodes using JPA with the following mapping @OneToMany (cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "owner") private List<Bikes> bikes; I am having the issue of the orphaned roles hanging around the database. I can use the @org.hibernate.annotations.Cascade Hibernate specific tag but obviously I don't want to tie my solution into a hibernate implementation. Any pointers greatly appreciated.

• deep or shallow copying?

  - by Dervin Thunk

  Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?

• Find out the number of digits of min/max values of an integral type at compile time

  - by Checkers

  Is there a way to find out the number of digits of min/max values of an integral type at compile time so that it's suitable to be placed as a template parameter? Ideally, there will be an existing solution in, for example, Boost MPL. Failing that I'm looking for some pointers for a hand-coded solution.

• Why use an event cache with epoll_wait?

  - by user1827356

  Question: epoll man page has some pointers when using epoll with an 'event cache'. But, why would you need to maintain an event cahce at all - Isn't this the same as what epoll is supposed to be doing? Is it to avoid making multiple epoll_wait calls which might be slower than managing the events in user space? Is it to implement a custom 'priority' scheme over the cached events? Background: I'm trying to understand the strengths/shortcomings of epoll and its applicability to different situations
