    1. COIt depends on what the algorithm is, how often you apply it, and when you need to apply it (compile time, load time, run time?). Can you give more details?

    2. COAndrew, this algorithm is applied in run time(every time the texture is rotated). Considering that the texture can be rotated in every Update means that the algorithm should be applied before every Draw.

    3. COReally this is a performance question. Reading from a render target is one option. Using a pixel shader is generally the fastest method - but has many limitations - and then a host of techniques for overcoming those limitations. I'd need to know more information about the algorithm before I can narrow it down. Also what, exactly, do you mean by "rotated"? Are you moving vertices? Texture co-ordinates? Or something more complicated?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
