Loading a 3D Texture

#Edit - Still get the same problem on a Quadro 6000 with JPG or PNG

Unfortunately, I am still running into the same error, even when I copy and paste in your code.

I made a small subset of jpg images to see if there was a problem with the png format, and I still encounter the following error.

** ERROR: 'BodyScans/Test/3.jpg' cannot be loaded into depth 1 of 3D texture. Valid range is 0-0
** ERROR: 'BodyScans/Test/4.jpg' cannot be loaded into depth 2 of 3D texture. Valid range is 0-0
** ERROR: 'BodyScans/Test/5.jpg' cannot be loaded into depth 3 of 3D texture. Valid range is 0-0
** ERROR: 'BodyScans/Test/6.jpg' cannot be loaded into depth 4 of 3D texture. Valid range is 0-0

Do you happen to know what the error is exactly referring to for the 0-0 range?

I end up just having the first texture applied to the object.

I am developing on a laptop using an NVIDIA GTX 675M.
Are 3D Textures not be supported on these cards? Couldn't find any documentation only

I'll give it a shot on a Quadro in a few minutes.

Thank you,
George

Can you post the copy/pasted code you are running? Your original code sample was not using viz.addBlankTexture to create the 3D texture and specify the depth dimension.

I am now using your code and I still get the same error.
Only difference is I change the images being used to a different directory.

import viz
viz.go()

#Create list of 2D images that will make up 3D texture
files = [ 'BodyScans/Test/'+ str(i+1) + '.jpg' for i in range(1,6) ]

#Create blank 3D texture
tex = viz.addBlankTexture([512,512,len(files)],viz.TEX_3D, minFilter=viz.LINEAR_MIPMAP_LINEAR)

#Load each image into 3D texture
for i,f in enumerate(files):
	tex.load(f,i)
	
#Apply texture to quad
quad = viz.addTexQuad(pos=(0,1.8,2),texture=tex)

#Create slider to change z texture coordinate of quad
slider = viz.addSlider(pos=(0.5,0.1,0))
def SetDepth(pos):
	m = viz.Matrix.translate(0,0,pos)
	quad.texmat(m)
vizact.onslider(slider,SetDepth)


viz.startlayer(viz.QUADS)

#Lower left
viz.texcoord(0,0,0)
viz.vertex(0.4,0.01,0)

#Upper left
viz.texcoord(1,0,0)
viz.vertex(0.4,0.05,0)

#Upper right
viz.texcoord(1,0,1)
viz.vertex(0.6,0.05,0)

#Lower right
viz.texcoord(0,0,1)
viz.vertex(0.6,0.01,0)

otf = viz.endlayer(parent=viz.SCREEN,texture=tex)

What version of Vizard are you using? And to be clear, do you get any errors if you run the original script I posted, without any changes?

[shivanangel]

I'm running 4.06.0138

I get no errors with your code.

[farshizzo]

Can you run the following script and post the entire output?

import viz
viz.go()

#Create list of 2D images that will make up 3D texture
files = [ 'BodyScans/Test/'+ str(i+1) + '.jpg' for i in range(1,6) ]

#Create blank 3D texture
tex = viz.addBlankTexture([512,512,len(files)],viz.TEX_3D)
print tex.getSize()

#Load each image into 3D texture
for i,f in enumerate(files):
	tex.load(f,i)
