Custom everpano raycaster implementations

Hi,

You can make usage of the everpano raycaster for your own implementations.

everpano raycaster

The navigator plugin provides those 2 public functions to get information about 3D positions of your model

plugin[navigator].ev_mousetomesh
plugin[navigator].ev_raytomesh

** Of course a requirement is that the project is done using everpano 3D, it won't be valid otherwise.

ev_mousetomesh : transform the mouse position into a 3d position of the mesh
ev_raytomesh : transform a ray which has origin vector and direction vector into a 3d position of the mesh

Demo of usage : 

<events name="everpano_raycaster" keep="true"  
onclick="plugin[navigator].ev_mousetomesh(get(mouse.x),get(mouse.y),my_d,my_x,my_y,my_z,my_nx,my_ny,my_nz,my_rx,my_ry,my_rz); 
    debug('distance : ',my_d); 
    debug('position'); 
    debug('x : ',my_x); 
    debug('y : ',my_y); 
    debug('z : ',my_z); 
    debug('normals'); 
    debug('nx : ',my_nx); 
    debug('ny : ',my_ny);
    debug('nz : ',my_nz); 
    debug('rotation'); 
    debug('rx : ',my_rx); 
    debug('ry : ',my_ry); 
    debug('rz : ',my_rz); 
" 
/>


the ev_raytomesh is expecting an origin position vector XYZ and a direction vector XYZ
plugin[navigator].ev_raytomesh(ox,oy,oz,dx,dy,dz,my_d,my_x,my_y,my_z,my_nx,my_ny,my_nz,my_rx,my_ry,my_rz);
If the ray that we generated intersects with the mesh we are going to get the same values as above saved in the variables name that we provided.

Happy coding

Kind regards

Hello,


I found that some of the cube faces could not get the correct mesh coordinates, but I have drawn cubes in Everpano.
In the third picture, for example, I couldn't get the right coordinates on the side.


Hope this helps.

Hi,

Quoted from "cejune"

could not get the correct mesh coordinate

If you can provide the project file we can take a closer look.
