    1. COI'm a bit confused, so you are saying that the alpha mask does not have to be a CCRenderTexture? If its not then how will I compare the alpha values in the other fragment shader for masking? If it is a CCRenderTexture then should I generate it using Ray's method i.e. instead of generating random colours, I should generate the white color 1.0,1.0,1.0,1.0?

    2. COThank You Pat, you have made my day :) A thing I noticed while implementing your solution, _hillVertices[_nHillVertices].y was returning a value of 0 when I printed the value in the console. So I took pt0.y and pt1.y respectively and divided those values by 512. Now I have a really good fit underneath the path, but sometimes as I move along the path I have noticed the sprite is a bit skewed towards the right. This might have to do with some x values, but anyways thanks again for your help!

    3. COThank You, it works beautifully now. But there is still a small problem, the sprite I am using to display under the path has some shapes drawn to display grass and other things, these are all getting squished down because I am binding a 512x512 (1024x768) sprite in my draw. Is there some way to rectify this problem? This is why I was trying to use the masking technique, I faced this problem too when I used Ray's code in OpenGL 1.1, i.e. the sprite gets squished. It works fine if I have a plain sprite with a solid color though :)

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.
