إنشاء تأثير عدسة عين السمكة على مشهد 3D وحفظ في صورة

Rereate تأثير عدسة ishisheye

في هذه المقالة ، نقوم بإنشاء كاميرا واثنين من الأجسام الخفيفة لالتقاط المشهد ، وكذلك إنشاء هدف تقديم ، وإنشاء منفذ عرض وتنفيذ إسقاط السمكة بعد المعالجة مع خريطة المكعب كمدخل وأخيرا حفظ نسيج السمكة. تسمح طريقة execute لفئة Renderer بتنفيذ تأثير معالجة النشر وحفظ النتيجة لتقديم الهدف.

This code example creates a Fisheye lens effect on 3D scene and save into the image format.

Python


import aspose.threed as a3d
from aspose.pydrawing import Color
from aspose.pydrawing.imaging import ImageFormat

#load the scene

scene = a3d.Scene.from_file("test.glb");

#create a camera for capturing the cube map

cam = a3d.entities.Camera(a3d.entities.ProjectionType.PERSPECTIVE)

cam.near_plane = 0.1
cam.far_plane = 200
cam.rotation_mode = a3d.entities.RotationMode.FIXED_DIRECTION

scene.root_node.create_child_node(cam).transform.set_translation(5, 6, 0)



#create two lights to illuminate the scene

light = a3d.entities.Light()
light.light_type = a3d.entities.LightType.POINT

scene.root_node.create_child_node(light).transform.set_translation(-10, 7, -10)


light = a3d.entities.Light()
light.color = a3d.utilities.Vector3(Color.cadet_blue)


scene.root_node.create_child_node(light).transform.set_translation(49, 0, 49)


#create a renderer

with a3d.render.Renderer.create_renderer() as renderer:

    #Create a cube map render target with depth texture, depth is required when rendering a scene.
    rt = renderer.render_factory.create_cube_render_texture(a3d.render.RenderParameters(False), 512, 512)

    #create a 2D texture render target with no depth texture used for image processing
    final = renderer.rendere_factory.create_render_texture(a3d.render.RenderParameters(False, 32, 0, 0), 1024, 1024)



    #a viewport is required on the render target
    rt.create_viewport(cam, RelativeRectangle.from_scale(0, 0, 1, 1))

    renderer.render(rt)


    #execute the fisheye projection post-processing with the previous rendered cube map as input
    #the fisheye can have field of view more than 180 degree, so a cube map with all direction is required.

    fisheye = renderer.get_post_processing("fisheye")

    # we can change the fov to 360 instead of the default value 180.

    fisheye.find_property("fov").Value = 360.0

    #Specify the cube map rendered from the scene as this post processing's input

    fisheye.input = rt.targets[0]

    #Execute the post processing effect and save the result to render target final

    renderer.execute(fisheye, final)

    #save the texture into disk

    final.targets[0].save("fisheye.png", ImageFormat.PNG)
