Case sensitivity on Linux #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Build the chapter 7 PointSprites example on Linux
2. Run the example

What is the expected output? What do you see instead?
You get a black screen instead of a field of stars

What version of the product are you using? On what operating system?
Ubuntu 10.10

Please provide any additional information below.
The problem is the source code references 'Star.tga', while the actual filename 
is 'star.tga', causing the loading of the file to fail.

The same for the Ch7 TextureArrays example with 'include <Stopwatch.h>' and 
'StopWatch.h'.

The 'Star.tga' issue is in TextureArrays as well.

Ch5 Sphereworld has Marble.tga, Marslike.tga and MoonLike.tga on the filesystem 
and all lowercase names in the code.

Not a rant but I'm (highly) surprised that the author of such a respected 
OpenGL book in its 5th incarnation (still) commits such basic/childish 
mistakes, which is somewhat understandable if he only coded for windows or for 
those macs installed on a fs with case sensitivity disabled.

I noticed that the vertex shader for the linux program does not actually change 
the size of the sprite as it gets closer. Its looks pretty much even. The vp 
located in the Src folder correctly increases the size of the sprites as they 
get closer.

I took the vp in the Src, speeded it up and also included a better algo for 
feeding stars back into the view frustum as they leave...

Try it out...
