Water Reflection & Sky?

[Umnik]

Hello everyone!

Today, doing the mapping of water in my project.

All done through the lesson.

Explain why I do not see the sky on the surface of the water?

[Marleys Ghost]

code example?

 

how have you set the reflections?

TBuffer gbuffer=CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);


TBuffer lightbuffer=CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH);
TBuffer reflectionbuffer=CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);//gbuffer for rendering reflections
TBuffer reflectionlightbuffer=CreateBuffer(GraphicsWidth(),GraphicsHeight(),BUFFER_COLOR|BUFFER_DEPTH);//buffer for rendering reflection lighting to

Sample from tutorial clear!

Is this from the rendering water tutorial?

I'm still very new at this, but I loaded my scene using the example posted in this thread:

 

http://leadwerks.com/werkspace/index.php?/topic/381-scene-loading-example/

 

 

It uses the SetSkybox() function in "Framewerk.h"

 

// Load Skybox

fw.GetRenderer().SetSkybox(LoadMaterial("abstract::FullskiesBlueClear0016_2_L.mat"));

 

It doesn't look like you're using Framewerk, but you may want to look for the SetSkybox() function in "Framwerk.cpp" to see exactly what it is doing. It reflects everything correctly in my scene.

 

Hope that helps

SkyBox I displayed correctly.

 

I do not booming like never before displaying on the surface of water.

[Umnik]

Is anyone a example of how to create a reflection on the water?

Without the use of third-party libraries?

Thanks!

Framewerk is not a 3rd party library, it's part of LE. It makes really no sense not to use it. If more features and customizations are needed in Framewerk, they can be added, but so far nobody (except Michael Betke) hasn't really said what they would like to see added to it. In the C++ version it would be easily possible to add a hook or callback to have your own custom postshaders added. It should be possible in the BlitzMax version too.

Thanks!

I agree with Lumooja it really makes no sense not to use framewerk. Plus most of the tutes need updating for the more recent versions of the engine, which I think Josh is in the middle of right now.
