blender016晴天娃娃

这是 oeasy 系统化 Python 教程，从基础一步步讲，扎实、完整、不跳步。愿意花时间学，就能真正学会。晴天娃娃的制作_设置位置和旋转

开始

配套视频
上次我们

深入理解了清场
原来只是删除了对象
并没有删除实际的

网格
灯光
摄影机

想做个晴天娃娃

怎么做呢？🤔

制作三个球体

白色的为头部
黑色的为眼球

眼球参数

一会儿要用

如何使用代码生成?

代码生成头部

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() head = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "head"

生成头部

生成左眼

import bpy bpy.ops.object.select_all(action="SELECT") # 选择所有物体 bpy.ops.object.delete() # 删除选定的物体 head = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3)

效果

准备上色

上色

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() head = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) mat = bpy.data.materials.new('mat_eye') mat.use_nodes = True color = (0, 0, 0, 1) mat.node_tree.nodes["Principled BSDF"].inputs['Base Color'].default_value = color bpy.context.object.data.materials.append(mat)

效果

另一只眼睛

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() head = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) mat = bpy.data.materials.new('mat_eye') mat.use_nodes = True color = (0, 0, 0, 1) mat.node_tree.nodes["Principled BSDF"].inputs['Base Color'].default_value = color bpy.context.object.data.materials.append(mat) l_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "l_eye" bpy.context.object.location = (0.7, -0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) bpy.context.object.data.materials.append(mat)

红眼睛的效果

可以控制层次结构吗?

层次结构

左右眼对象

隶属于脑袋

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() bpy.ops.mesh.primitive_uv_sphere_add() head = bpy.context.object bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) mat = bpy.data.materials.new('mat_eye') color = (0, 0, 0, 1) mat.use_nodes = True mat.node_tree.nodes["Principled BSDF"].inputs['Base Color'].default_value = color bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head l_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "l_eye" bpy.context.object.location = (0.7, -0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head

效果

左眼、右眼两个对象

成为 head 的字对象

增加一个身体

添加一个圆锥体

并修改参数

将添加身体圆锥的操作

转化为代码

代码化

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() bpy.ops.mesh.primitive_uv_sphere_add() head = bpy.context.object bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) mat = bpy.data.materials.new('mat_eye') mat.use_nodes = True color = (0, 0, 0, 1) mat.node_tree.nodes["Principled BSDF"].inputs['Base Color'].default_value = color bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head l_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "l_eye" bpy.context.object.location = (0.7, -0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head bpy.ops.mesh.primitive_cone_add() body = bpy.context.object body.name = "body" body.location = (0,0,-1) body.scale = (1,1,2)

可以加上双手和双脚吗?
可以带上帽子或者眼镜吗?
可以添加鼻子和耳朵吗?
这个任务就交给你了

再封装

现在场景中有两个对象

head
body

可以把身体和头部

整合成一个角色吗?

再封装

把head、body

封装进 character

import bpy bpy.ops.object.select_all(action="SELECT") bpy.ops.object.delete() bpy.ops.mesh.primitive_uv_sphere_add() head = bpy.context.object bpy.context.object.name = "head" r_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "r_eye" bpy.context.object.location = (0.7, 0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) mat = bpy.data.materials.new('mat_eye') mat.use_nodes = True color = (0, 0, 0, 1) mat.node_tree.nodes["Principled BSDF"].inputs['Base Color'].default_value = color bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head l_eye = bpy.ops.mesh.primitive_uv_sphere_add() bpy.context.object.name = "l_eye" bpy.context.object.location = (0.7, -0.5, 0.3) bpy.context.object.scale = (0.3, 0.3, 0.3) bpy.context.object.data.materials.append(mat) bpy.context.object.parent = head bpy.ops.mesh.primitive_cone_add() body = bpy.context.object body.name = "body" body.location = (0,0,-1) body.scale = (1,1,2) character = bpy.data.objects.new("character", None) bpy.data.collections["Collection"].objects.link(character) head.parent = character body.parent = character

制作成功

可以封装成函数吗?

函数
