[JAVA3D] Signed intensity detail textures

I wish to "add" intensity to the base texture during the multi-texturing pass, or if necessary a second pass. With multipass and blending function glBlend(GL_DST_COLOR,GL_SRC_COLOR) or glBlendFuncGL_ONE, GL_ONE(GL_ONE, GL_ONE), everything above 0.5 brightens the color. I am unclear how to apply

Hello Kevin, Isn't that a bit counter intuitive? Normally, in the world of math, when people talk about normalizing a vector, matrix, or other tensor (call it T), they mean that they adjust it such that |T|=1, where |T| is a norm, usually the L2 (euclidian) norm. In general this is done by setti

This is a known limitation in Java 3D. For Java 3D 1.3 we are going to add an explicit attribute (in the View) to control separate specular color. Btw, some OpenGL cards may not support this feature since it requires an OpenGL extension. On those cards, the separate specular color enable will b

Re: [JAVA3D] Opengl - specular highlight on texture not working

Java 3D specifies that using a seperate specular color when doing texture mapping is the prefered way to render objects. An acceptable fallback is to use a single lighting color, and apply textures after that. Our Direct3D version currently supports seperate specular color, so the specular highl

[JAVA3D] I'd like to "anti-alias" small polygons

VisAD includes code to convert fonts to small polygons for 3-D rendering. Each character converts to many polygons, typically 50 to 70 polygons. However, the characters are very hard to see when we zoom out. One possible fix might be anti-aliasing, but it only seems to apply to lines and points,

No, the normalize methods ensure that the column vectors are orthogonal to each other. It does not alter the scale. (Earlier versions of Java 3D had a bug that would force the scale to 1.0, but that was never the intent). The main use of these methods is to correct for floating point errors tha

Perhaps you could use AxisAngle4d or AxisAngle4f? The Java Docs describes an axis angle as a rotation of angle (radians) about the vector (x,y,z). An axis angle can be used to set a Transform3D object. Hope this helps. Joe -Original Message- From: silvano [mailto:[EMAIL PROTECTED]] Se
