Create Mirror texture

[Farlas]

Hello there i was starting to do some thing with leadwerks and i was thinking about to create a mirror where we can see all stuff around the mirror like a real mirror but i see only topic about cubemap to do reflections with a predefined texture.

 

so there is a way to do a simple materials for making a true mirror ?

Simple way? not really, you could do it with a camera, render buffer and render to a texture.

if you do a mirror then presumeably you would have to show an image of a human when the controller is in front of the mirror or whatever the controller is supposed to be. Intiguing but not easy.

i have try to use similar methode of waterplane cause the waterplane can reflect all environement like a miror but no success.

 

so i continue to try until i find something.

As far as I am aware the water shader used requires a plane thats facing directly up, so you'd probably have to write your own reflection shader to uses a plane in a different orientation. Your best bet is to use a camera, render buffer and render to a texture.

I think things like mirrors will need a lot of performance..

 

only thing i can think about is rendering the whole scene a second time, just using another camera (facing perpendicular to the surface of the mirror) rendering this scene to its own buffer and then applying the color-buffer to the mirror as a texture..

 

but as you see, rendering everything a second time (for one mirror) will not be very performant..

 

maybe there's a better way, but i dont know how..

I believe the shader will work with any orientation. It's the rendering that has to be oriented with the mirror.

The water shader I wrote only works with a vertical plane, but it is possible to modify the shader to work with any arbitrary plane.
