RenderScript分配中的调用单元格

Question

可以说我有一个分配要更改单元格x_0，y_0处的值的方法，是否可以通过调用来设置或获取单元格的值或运行仅对一个单元格运行的内核函数？

Answer 1

You should probably use rsSetElementAt_uchar4() or whatever data type it is that you are setting. http://developer.android.com/guide/topics/renderscript/reference/rs_allocation_data.html#android_rs:rsSetElementAt is a guide for this.

Alternatively, you can do a single cell kernel call via Script.LaunchOptions (which should have a nice reflected interface in your ScriptC_* files).

http://developer.android.com/reference/android/renderscript/Script.LaunchOptions.html and http://developer.android.com/reference/android/renderscript/Script.html#forEach(int , android.renderscript.Allocation, android.renderscript.Allocation, android.renderscript.FieldPacker, android.renderscript.Script.LaunchOptions)
