One with xterm colab festure and another with hull-convex known as lattrice with OllamaFunctions.

Blender 3D and python scripting - part 032.

Today I created an addon for Blender version 4.3.2 that allows me to select two folders to render 3D objects from the first folder and add 512px samples with these renderings to the second folder.

This is what the addon installed in Blender 3D looks like:

Here's what the source code of this addon looks like:

Blender 3D and python scripting - part 031.

This python script for blender will select vertrices based on boolean ...

This is the result with Blender version 4.3 :

This is the python script:

import bpy, bmesh

obj = bpy.context.active_object
me = obj.data

bpy.ops.object.mode_set(mode = 'EDIT') 
bpy.ops.mesh.select_mode(type="VERT")


bm = bmesh.from_edit_mesh(obj.data)
selected = [False,False,True,True,True,True,True,True]
verts = [vert for vert in bpy.context.active_object.data.vertices if vert.select]
all = [vert for vert in bpy.context.active_object.data.vertices]
print("selected:",len(verts))
print("all:",len(all))
bpy.ops.object.mode_set(mode = 'OBJECT')
me.vertices.foreach_set(
"select",
selected
)
bpy.ops.object.mode_set(mode = 'EDIT')

Python 3.10.12 : Simple test with diffusers to create texture.

Today I tested on colab a simple python script to generate a texture using: diffusers, torch and gradio.

I upload the notebook on my colab repo from GitHub.

The script is simple and works good:

import gradio as gr
from diffusers import StableDiffusionPipeline
import torch

model_id = "dream-textures/texture-diffusion"
pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16)
pipe = pipe.to("cuda")

def generate_image(prompt):
    image = pipe(prompt).images[0]
    image.save("result.png")
    return image

iface = gr.Interface(
    fn=generate_image,
    inputs="text",
    outputs="image",
    title="Stable Diffusion Image Generator",
    description="Introduceți un prompt pentru a genera o imagine folosind Stable Diffusion."
)

iface.launch()

The result for the pbr winter terrain is this image:

Python 3.13.0 : Only the unstructured library in Fedora 41 ...

The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. The use cases of unstructured revolve around streamlining and optimizing the data processing workflow for LLMs. unstructured modular functions and connectors form a cohesive system that simplifies data ingestion and pre-processing, making it adaptable to different platforms and efficient in transforming unstructured data into structured outputs.

I used pip tool to install this python package:

Python 3.13.0 : emoji symbols with PIL.

Today I want to use emoji symbols and I wrote this python script:

from PIL import Image, ImageDraw, ImageFont
import os

# Font size and image dimensions
font_size = 88
width = 640
height = 480

# Use Symbola.ttf from current directory
font_path = "Symbola.ttf"

# Create image
img = Image.new('RGB', (width, height), color='white')
draw = ImageDraw.Draw(img)

# Get font
font = ImageFont.truetype(font_path, font_size)

# Emoji matrix
emoji_matrix = [
    ['😀', '😁', '😂', '🤣', '😃'],
    ['😄', '😅', '😆', '😇', '😈'],
    ['😉', '😊', '😋', '😌', '😍'],
    ['😎', '😏', '😐', '😑', '😒']
]

# Calculate spacing
x_spacing = font_size + 10
y_spacing = font_size + 10

# Calculate starting position to center the grid
start_x = (width - (len(emoji_matrix[0]) * x_spacing)) // 2
start_y = (height - (len(emoji_matrix) * y_spacing)) // 2

# Draw emojis
for i, row in enumerate(emoji_matrix):
    for j, emoji in enumerate(row):
        x = start_x + (j * x_spacing)
        y = start_y + (i * y_spacing)
        draw.text((x, y), emoji, font=font, fill='black')

# Save the image
img.save('emoji_art.png')
print("Emoji art has been created successfully! Check emoji_art.png")

The result image named emoji_art.png is this:
