Requirements: Surface Effects

Textures

Create a texture from a file that is suitable for the ground. Use texture unit $1$

Immediately after creating this texture using init$\_$texture$\_$from$\_$file, set the wrap method for both S and T to mirrored repeat.Use the function glTexParameteri with the binding point GL$\_$TEXTURE$\_2$D$.$You will find examples of that code in module $5.$

Create three $2$D textures that will be used on the columns Use texture units $2,3,$ and $4$Create a texture from a file that is a wood texture. This will be used on the rotating blocks. Use texture unit $0$

For columns

Set the diffuse color to a color with these components:

red $=$ x $*$ ca $/($number$-1)+$ cbgreen $=$ y $*$ ca $/($number$-1)+$ cbblue $=($x $+$ y$)*$ ca $/(2*$number$-2)+$ cb$)$Use the function cs$4722$::Color::colorRGB to create the color. Documentation of the function is on this pageThe values of ca and cb are already computed in the code.

Set the surface effect to $(2$x $+3$y $+4)\%5$Set the texture unit to $($y $\%3)+2$

For the rotating blocks

Set the surface effect to just use a textureSet the texture unit to $0$

For the ground

Set the surface effect to just use a textureSet the texture unit to $1$Set the texture$\_$scale of the ground block to number

In the fragment shader

Comment out the code assigning s$\_$color to fColor and add code that provides the following effects:surface effect $0$: s$\_$colorsurface effect $1$: diffuse colorsurface effect $2$: texture samplesurface effect $3$: mix s$\_$color and texture samplesurface effect $4$: mix s$\_$color and diffuse colorelse: $(0,0,1,1)$
