Can you share the source

[meming4]

how do you generate these shadows? ik the question has already been asked , but can you give me a more in depth reply? thnx

[AntCoder]

Easiest way to do this is to simply create a shadow map once per frame and modulate that in with the scene lighting pass. (Opposed to shadow volumes etc)

[otplanet666]

could you post your code that calc the dot procduct?

[OniLink10]

@otplanet666 Dot Product is easy to calculate. Shouldn't you do it yourself?

[mov0001000]

The shadows don't merge correctly.

[zoser]

yeah , but this is an old video

[ArkanRow]

Cool!!

[TheForce]

how do you generate those shadows?

[zoser]

With the position of the light and the position of each vertex, project a poligon with alpha...

if the dot product between the light and the normal of the surface is < 0 draw the shadow

[spider853]

Its volume shadows?
