Gradient of color
Hi, I'm trying to create a gradient shade for a sphere with alpha(0.1). May I know how can it be done in vizard? Currently, the shade is constant throughout the sphere.
My objective is to create a blue atmosphere around the earth that is darker on both ends. Alternatively, I'm also trying to generate a glowing effect around the earth to improve but not sure how can I do it. Appreciate your advice. The Earth object is a OSGB file created in 3ds Max. code: import viz import vizshape import vizfx viz.setMultiSample(8) viz.fov(60) viz.go() earth = viz.addChild('earth.osgb') earth.setScale(0.01,0.01,0.01) earth.setPosition(0,1,0) earth.addAction( vizact.spin(0,1,0,20) ) vizfx.addDirectionalLight(euler=(-45,90,45), color=viz.WHITE) earthAT = vizshape.addSphere(radius=2.2,slices=60,stacks=60, axis=vizshape.AXIS_Y) earthAT.setPosition([0, 1, 0]) earthAT.color(viz.AZURE) earthAT.alpha(0.15) Thank you.
