Reflective water problem

Im not sure whats causing this but I wanted to see if anyone else has any ideas. The island reflects to much or something see how it has a longer reflection then it should. |
| ||
| The "sun"'s not high enough? |
| ||
| its a reflection not a shadow and there isnt a sun :P |
| ||
| To use an old nautical expression, maybe it has something to do with the angle of the dangle, as Long John Silver oft used to say. Anyhow how are you making this reflection. Give a clue, you know X marks the spot, that sort of thing. |
| ||
| How much of the island is under the water surface? I've seen similiar effects on objects positioned to low into the reflection plane. [img  /] |
| ||
| yeah that is the problem im currently playing with it now to try and fix it. |
| ||
| Heh - that was posted at 1am - sorry - bit tired. I still havent got any ideas :( |
| ||
| Don't know how you render the reflection, but the solution in Ogre was to add a clippingplane to the camera which simply cuts away anything below the reflectionplane. |
| ||
| yeah... that's most likely it, part of the island is below the water... i had to insert an algorithm to hide the sub models and show a different mesh (only the top half of the sub) during the cubemapping 'capture' in order to avoid this sorta thing... --Mike |

| you can solve the issue with careful programming and the DX7test DLL by Tom. I'm a tad busy at work at the mo, But I'll post working screenshots and if i get time later, explain it. [edit] Couldn't find the screenies :( |

| Don't know how you render the reflection, but the solution in Ogre was to add a clippingplane to the camera which simply cuts away anything below the reflectionplane. Slick! I'm guessing this would solve the problem for cubemap reflections where objects are intersecting (eg. Red's sub.) |
| ||
| Um, how do you add a clippingplane? |
| ||
| I don't think Blitz does it automagically, but don't fear! There's a really fast clipping plane demo in the code archives which I have always wanted to put to use. http://www.blitzbasic.com/codearcs/codearcs.php?code=1143 |
