Constructor & Destructor Documentation

Arrows::Arrows

(

QWidget *

parent = 0

)

nk - connect navigation with setRes & setPointSize

nk - choose color for arrows : tbd: modify shader

Member Function Documentation

void Arrows::draw

(

)

TEST Velocity & points

if xTick is reached -> place vertex and increase xRes

blend point sprites with bg texture

nk - set current arrow color -> black does not work because of blending with background (not texture)

nk - set active textur unit explicit!!!

nk - current index in dataset array

null-vector

FlowChannel* chZ = m_flowData->getChannel(Z); // nk - we use only x/y to draw in plane

nk - now corrected version of drawing arrows

get already normalized velocity vector - only use x,y becaus of plane

nk - calc angle of arrows

set normal point size

bind shader

set angle in shader

nk reset current color back to old one
